During my recent visit to the Cody Firearms Museum I was lucky enough to examine a number of interesting firearms (more videos soon). In this video we take a look at a Winchester Model 1905 chambered in .45 ACP.
The Model 1905 was originally designed by Thomas Crossley Johnson, as a commercial rifle chambered in either .32 or .35 Winchester Self Loading. It was the second of a series of blowback operated rifles Johnson designed between 1903 and 1910.
The origins of this gun, however, are less clear. It is part of the Cody Firearms Museum’s impressive collection and is believed to be a Winchester-made prototype. Dating the rifle is more difficult. It was originally believed to have been developed during the First World War but the Winchester Arms Collection’s records date the rifle to 1919. It has also been suggested that the conversion may have been developed by Winchester as an auxiliary arm for the US Army, as a replacement for the 1911 pistol for some troops – much along the lines of the later .30 carbine. There are no records, however, to suggest the .45 ACP Model 1905 was ever officially tested.
Herbert Houze, former curator of the Cody Firearms Museum, believed the conversion was actually developed after World War Two. No patents or Winchester documents are known to refer to it but Houze believed that one of Winchester’s engineers, Harry H. Sefried, developed the conversion as a side project with a potential aim to interest law enforcement agencies in a carbine chambered in the readily available .45 ACP round.
Taking a stock rifle a number of changes were made, the rifle was re-barrelled and rechambered for the .451-inch .45 ACP round and the bolt face was modified slightly. The 1905 originally fed from straight 5 or 10-round box magazines. In order to feed from a Colt 1911 magazine a new magazine housing was added. The curved front of the trigger guard has been machined back and is now flush with the rear of the conversion housing which appears to be integral to the lower receiver’s frame. On close inspection we can clearly see that parts have been brass brazed together around the original magazine release and inside the magazine well.
The rounded magazine housing has a new magazine release positioned at the front of the magazine, as in the 1911 and allows the magazine to be inserted at an angle. The ejection port has also been altered with an additional cut-out being made at the top to aid ejection.
Take down remains the same, with the upper and lower separating once the take down screw at the rear of the receiver is loosened. The conversion appears to be well thought out and the finish and care taken would indicate this was rifle wasn’t a rough proof of concept prototype. Sadly, there is no information on how the conversion performed.
Regardless of the origins of the conversion Winchester never offered the chambering commercially and this prototype is the only example known to exist. Today, it is held by the Cody Firearms Museum at the Buffalo Bill Centre of the West in Wyoming. The museum has just undergone a major renovation and is well worth visiting. Our special thanks to the CFM for letting us examine this rare rifle.
Herbert Houze, the former Curator of the Cody Firearms Museum who is mentioned in this article and video, recently passed away – this video is dedicated to his memory.
The rifle we’re examining is one of dozens of designs sold by the Brownings to the Winchesters Repeating Arms Company during their long relationship. This design dates from the early 1890s and represents one of Browning’s numerous attempts to move away from the tube magazine-fed designs favoured by Winchester.
The prototype is based around the lever-actuated vertically sliding locking block patented by Browning in May 1884 and first used by Winchester in the Model 1886. The rifle itself is in the ‘military musket’ configuration with full-length handguards, military sights, a cleaning rod and able to mount a bayonet.
The rifle is chambered in a .45 calibre cartridge, likely .45-70, and weighs just over 9lbs. Browning patented the design of the rifle and magazine in August 1891, with the patent being granted in December (US #465339). It is attributed to John Moses Browning and his younger brother Matthew S. Browning.
The most interesting feature of the rifle is its detachable box magazine. The magazine is held in place by a spring-loaded catch at the front of the magazine which locks against a tab in the magazine’s wall.
It differs from the box magazines previously developed by James Paris Lee, which Lee begun developing in the mid-1870s (see examples listed below). It’s a simple design with a follower powered by a coil spring. The prototype mag itself is made from pressed metal and is held together with some rough welds. Unlike the magazines we’re familiar with today, the top of the Browning’s magazine is almost entirely enclosed with only a small opening at the rear. The rounds would be loaded nose-first with their rims sliding into the channel at the rear of the magazine.
The single-stack magazine appears to hold around five rounds, with Browning’s patent supporting this. The position of the magazine, in front of the action – not below it, is a hint at how it worked. An almost fully enclosed magazine does have its advantages – it would have prevented dirt from entering the mag and it also overcame the need for feed lips which were susceptible to damage, one of the elements which took Lee some time to perfect.
So How Did The Magazine Work?
There is a shoulder on the underside of the bolt which caught the rim of the cartridge which was protruding from the magazine. The bolt pulled the cartridge backwards, out of the magazine and onto a cartridge lifter. As the lever reached its full forward travel the lifter then elevated the round up into line with the breech. When the lever was cycled back again the round was pushed off the lifter and chambered, just as in a normal tube-fed Winchester. As the lever reached the end of its return travel the locking block rose to locked the action.
The prototype has a sliding safety bar that locks the lever and blocks the trigger. The trigger differs from the Model 1886 as it is integrated with the lever. In the photograph below we can see the locking block descended, with the lever forward, and the breech block to the rear with the action open. We can also see the striker assembly at the rear of the bolt. The striker cocks on closing when the lever is returned rearward.
It’s quite an exposed action, with the entire top of the action open. With the action closed in the photograph below we can see the extractor running along the right side of the bolt.
It’s clear from the design of the magazine that Browning didn’t intend the rifle to be reloaded with stripper clips, although single loading of the rifle itself (not the magazine) would have been possible. When compared to other contemporary system this would have been somewhat of a disadvantage compared to Lee’s magazine’s later loading with chargers and stripper clips. However, from examination of Browning’s 1891 patent his intention becomes clear, the patent explains that he intended for the magazine itself to be replaced:
“One magazine may be readily removed from the gun and another introduced in its place, so that the person, using the arm may have at hand several magazines to be interchanged as the cartridges from one magazine are exhausted.”
This is a concept that wouldn’t be accepted by militaries for decades. Winchester purchased the rights to the design but this was one of many designs Browning sold the company which never saw production. The design and prototype are fascinating and represent one of Browning’s lesser-known concepts.
This rifle is a unique prototype and it was a true honour to examine it. It’s now on display at the newly refurbished Cody Firearms Museum, at the Buffalo Bill Centre of the West. The new museum is phenomenal and well worth a visit. Our thanks to the museum for allowing us to film items, like this one, from the museum’s collection.
While doing some research into the British Army’s breechloading trials for another upcoming episode I came across an offshoot report into repeating rifles. This offshoot trial tested the repeating rifles that were then available, not with the goal of selecting one to adopt, but to see what was currently available.
Following the Prussian Danish War of 1864 and the decisive advantage the breechloading Dreyse Needle Gun gave the Prussians most of Europe scrambled to make the transition to breechloaders. In 1865 the British Army began a series of trials examining new breechloading rifles. The aim was first to find an adequate conversion as a stopgap measure – Jacob Snider’s action won that competition, but also to find the ideal breech-loader that was best suited to service all around the British Empire – the Martini-Henry was eventually adopted.
But as an offshoot to these breechloading trials the Army also carried out testing on new repeating arms. I like many people have often wondered why the Winchester lever action or other repeaters weren’t taken more seriously by European powers during the 1860s. Today, we’re going to take a look at the February 1869 report on repeating arms and try to answer that question.
A testing committee headed up by Lt Colonel H.C. Fletcher (of the Scots Fusilier Guards) with officers from the 48th and 3rd regiments began examining repeating rifles in 1867. Six repeating rifles were tested, the Henry, the Ball & Lamson, the Larsen, the Spencer, the Vetterli (misspelled ‘Vertelli’) and the Winchester Musket. The Norwegian Larsen was provided without ammunition and was quickly dropped due to concerns about the safety of its action. The Vetterli and Winchester were added during the later stages of the trials. As I mentioned the aim wasn’t to select a repeater for adoption rather to get an idea of what was available. So the trials weren’t exhaustive but they did test for accuracy and ran the guns through sand tests.
To test accuracy 20 rounds were fired at 2 targets at 500 yards to find the mean deviation, the Spencer was found to be the most accurate, while not surprisingly the Henry chambered in .44 Rimfire fared the worst. The rifles’ rates of fire were also tested: the Ball and Lamson fired 40 rounds in just under 3 minutes, the Spencer fired 14 rounds in 1 minute 33 before jamming and being dropped from testing, and the Henry fired 45 rounds in 1 minute 36 seconds. The rifles were also subjected to sand tests with the Ball and Lamson and Henry performing well, the Spencer, however, jammed and became unserviceable.
At this point the Committee liked the Henry best stating that it was “the most suitable for a military weapon” but that it would be better if it could be single loaded and the magazine held in reserve for emergencies. The late entry from Winchester was examined following the first round of tests, having heard about the improved Henry, Fletcher and the committee contacted Winchester and requested a rifle to test but it seems that some modifications were made at their request – probably to address the shortcomings of the Henry that had become clear in testing.
The exact configuration of the Winchester is a bit of a mystery. It wasn’t a standard Model 1866 Musket chambered in .44 Rimfire. The report describes it as a 50 inch long rifle, weighing 8lbs 12.5 oz, with a 29.75 inch barrel and a 12 round magazine. It chambered a .45 calibre, centrefire rather than rimfire round, with a 320 grain bullet. The Cody Firearms Museum, which houses the Winchester factory collectio,n has a number of prototype 1866-pattern rifles chambered in larger calibres than .44. The rifle tested by the British committee may have looked similar to those.
As the Committee contacted Winchester directly it is possible that they directly requested a rifle chambered in a larger, centrefire round to improve on the Henry’s poor accuracy at longer ranges. When tested at 500 yards the Winchester achieved groups with less than 1.5 feet of deviation and when pushed out to 800 yards managed 3.6 feet.
The rapidity of the Winchester was also tested and fired it managed 25 rounds in just 1 minute 18 seconds reloading 3 times. The new rifle included the new loading gate in the receiver, designed by Nelson King, this was seen as a much more practical method of loading.
When sand tested the Winchester, unlike the Henry, became jammed, with its lever becoming bent and unserviceable. Despite the weakness of the lever the trials committee decided that the Winchester “was simpler in construction and better adapted to the purposes of a military weapon” than the other rifles and the Swiss Vetterli, which they described as not as well suited to “the purposes of a military rifle”. But the committee wasn’t prepared to recommend a repeater for general adoption based on the testing.
So why wasn’t the Winchester adopted, even in small numbers, it seems that a repeating rifle may have been useful for scouts or mounted infantry. The Committee’s final report in February 1869, concluded that while they felt the Winchester was the best of the rifles tested, and it could be improved further, it was believed that the heavy weight of the rifle when fully loaded and the complexity and weakness of the action made it “objectionable” for service. The committee felt that “the mechanism of the Winchester was more complicated than that of the Martini and many other single loaders; it is also more liable to injury, and not so well calculated to resist the wear and tear of service.”
The Committee, however, could see the benefits of rapid magazine-fed fire, with the report stating “there may, however, be occasions when a repeating arm might be useful” As a result the Snider-Enfield remained in service and was replaced during the 1870s by the Martini-Henry, it wouldn’t be until the adoption of the Lee-Metford in 1888 that the British Army adopted a repeating rifle.
This article has only examined British opinion on the repeating rifles of the period and has not explored how other European nations felt about their military applications and value. Indeed, much has been made of Turkish use of Winchester repeating rifles during the Russo-Turkish War (1877–78) but that’s a topic for another day. This 1869 report is merely one case study, from one country, but it does add some interesting perspective. Hopefully the wider reaction to repeating rifles during the late 19th century is a subject we can touch upon in the future.

Held in the collection of the Cody Firearms Museum (CFM), at the Buffalo Bill Centre of the West, is a most intriguing Cold War submachine gun. The weapon came from the collection of the old Winchester Firearms Museum, which the CFM inherited, it is not a test & evaluation weapon made by another company but a submachine gun designed and developed by Winchester. Those who know their Winchester history will know the company had no prior background in submachine gun design, instead being best known for their rifles and shotguns.
Very little is known about Winchester’s submachine gun project, but two prototype examples survive, an early ‘in the white’ model labelled ‘N2’ and another which Herbert Houze, the CFM’s former curator, designated ‘N4’ . The documentary evidence for the Winchester submachine guns is sparse, amounting to just entries in the Winchester Museum’s inventory and a faded battered item tag attached to N2. A confusing element is that the inventory simply refers to the two prototypes as N-1 and N-2, with no mention of an N4.
There is also believed to be original engineering drawings housed in the Winchester Archival collection, currently held by the McCracken Research Library, but searches by myself and library staff have been unable to locate these.
It is unclear if the tag from N2 is contemporary, perhaps added when the gun was handed over to Winchester’s museum, or if it was added later. In under 100 words it give us a short potted history of the N2 itself and the company’s programme to develop a submachine gun.
Houze suggests the development programme began in 1955 and the tag attached the N2 suggests that development ceased in 1957, whether this is solely for that gun or the entire programme is unclear. This would make Winchester’s weapon a contemporary of the famous Israeli UZI.
The tag describes the N2 as a 9mm blowback ‘NATO Burp Gun’, followed by the name A.A. Arnold, a Winchester engineer perhaps best known for writing a series of manuals for Winchester firearms, followed by ‘dropped Dec ’57’. In his 1994 book, Winchester Repeating Arms Company: Its History & Development from 1865 to 1981, Houze suggests that the weapons were designed by A.A. Arnold and Melvin M. Johnson in 1955, for possible adoption by NATO. The association with NATO might also be the origins of the ‘N’ prefix. I have been unable to find any published patents attributed to Arnold, Johnson or the company relating to the experimental submachine gun.
I contacted NATO’s Archives who advised that they were unable to find any reference or documentation relating to a direct NATO submachine gun requirement. Another possibility is that the weapon was developed to market more broadly to NATO member nations. The submachine gun market at this time in Europe, however, was already saturated by both wartime surplus and a new generation of guns, including the Sterling, the UZI, the Madsen M50, and the Carl Gustav m/45.
The reverse of the N2’s label documents the prototype weapon’s reliability and feeding problems. The tag states that the N2 did “not eject well” and that the bolt slide assembly was too heavy. It also highlights failures to cycle properly with extracted cartridge cases catching under the firing pin. The label then gives a brief description of some of the N2’s features: “fixed firing pin, 33x Mag. Folding stock.” Interestingly, it also notes that the weapon would be cocked by a rod – the hole for which had not yet been added. The tag ends with a suggestion that the heavy one piece bolt assembly should be lightened.
N2 itself also has a piece of masking tape, on the recoil spring assembly cover, with its serial number and calibre written on it, along with A.A. Arnold’s name and some words that are too difficult to make out, but include ‘feed’.
Houze has also suggested that Melvin Johnson, designer of the Johnson rifle and light machine gun who joined Winchester as a designer and adviser in the early 1950s for a short time, and Stefan Janson, designer of the Brtish E.M.2 bullpup and subsequent Winchester engineer, both worked on the project. However, I have been unable to find any documentary evidence of their involvement.
Examining the N2:
We can learn a lot from hands on examination of the two Winchester ‘N’ prototypes. Examining N2 we find that the receiver is made up of a piece of shaped sheet metal with a rounded upper half containing the barrel, bolt and cutouts for the grip points on the bolt assembly that allow charging. The bolt assembly rides over the rear portion of the barrel and projects back into the receiver. The lower section of the stamped receiver is rectangular and has a cut out for a separate magazine housing and fire control mechanism consisting of a trigger and push through safety – which we did not remove during disassembly. The N4 is missing its safety.
In the N2, the magazine housing is held in place by the stamped metal trigger guard which rocks into a notch behind the trigger and at the front interfaces with a notch in the magazine housing which has to be placed in the receiver at the same time, both are then held in place by a screw. This was changed in the later ‘N4’ with the trigger guard as a separate independent piece.
Winchester N2 Prototype Reassembly:
The side plates, muzzle end cap and recoil spring assembly cover all made from Aluminium – ostensibly to reduce weight. The submachine gun prototypes both use a pinch cocking method similar to that seen in the earlier British BSA WELGUN developed during WWII. The recoil spring proved to be too strong to cock easily, the addition of ‘rod’ cocking handle is suggested on the N2’s tag. The blued, later N4 prototype, however, is still lacking a conventional cocking handle. The pinch cocking method is not ergonomic, the user’s fingers could easily be caught by reciprocating bolt in charging cut outs in the receiver.
Another ergonomic consideration is the Winchester’s submachine gun’s unusually swept back pistol grip angle, the angle of the forward grip made by stock when folded is also similarly angled. Both the weapons have a push though safety selector just above the trigger (likely safe & fully automatic, but could not check as gun unable/difficult to cycle the prototypes easily). The weapon likely fed from a double stack, single feed magazine – either of an similar pattern to the MP40 or proprietary. The N4 seen in Houze’s 1994 book is shown with an MP40 magazine. UZI magazines fit the weapon but don’t lock into place.
The basic design does not change substantially between the prototypes with the control configuration, folding wire stock, pistol grip angle and magazine housing dimensions remaining the same. The N4, however, differs from the earlier prototype in a number of respects. The N4’s nose cap now fits over the rounded half of the receiver, rather than sitting flush and the cut outs in the upper receiver to access the bolt assembly for charging have been moved back slightly.
The later N4 model has pins in place of some of the screws used on the N2. The side plates have been replaced by a one-piece recoil spring assembly cover which projects back further over the magazine housing to the rear of the receiver. The most fundamental difference between the two is that it appears that the front part of the N4’s receiver has been significantly altered with the lower receiver at the front of the gun removed. It appears to have been replaced by the recoil spring assembly cover which appears to slot into the receiver. Sadly, we didn’t have time to disassemble the N4 to examine this.
The N4’s bolt assembly also has more serrations, in a slightly different orientation, on its bolt assembly gripping area, but still no charging handle as recommended on the N2’s tag. The ejection port on the blued prototype is also at a position closer to 12 o’clock when compared to the N2s.
The N2 has a metal trunnion block, that the recoil spring guide rod screws into, this is held in place within the receiver by a cross pin. The bolt appears to be removed through the rear of the receiver once the stock assmbly/end cap is removed and the bolt assembly freed.
The folding stock was retained by spring tension of the wire metal stock against a wingnut-shaped catch that is riveted onto the recoil spring assembly cover. The stock is locked by a spring loaded push button system similar to the MP40s, this is not particularly sturdy. The shape of the wire stock itself is reminiscent of the US M3. When folded the butt of the wire stock acts as a front grip, the retention of the stock is surprisingly strong and stable.
Intriguingly, the Winchester Museum inventory notes that the guns are designated the N-1 and N-2, with an additional wooden model of the ‘Nato Burp Gun’ being transferred along with a box of duplicate parts in steel for the N2’s aluminium parts.

Today we’re examining an intriguing firearm with a fascinating history. It is difficult to understate the potential importance of the Curtis Rifle. Despite being designed in Britain in the 1860s the firearm gained more notoriety when it was offered as evidence in a legal battle between the Winchester Repeating Arms company and Francis Bannerman. What makes the firearm most noteworthy, however, is its fundamentally unconventional layout. Designed by William Joseph Curtis in the mid-1860s, it is arguably one of the earliest ‘bullpups’ and almost certainly the first repeating bullpup.
For the purpose of this article it would be wise to first define what a bullpup actually is. It can be defined as a weapon with a somewhat unconventional layout which places the action and magazine behind the weapon’s trigger group. This has the benefit of maintaining a conventional rifle’s barrel length while making the overall length of the rifle more compact.
Bullpup rifles became popular with a number of militaries around the world during the 1970s and 1980s – namely the Austrian Steyr AUG, the French FAMAS and the British SA80, and more recently with rifles from China and Singapore as well as the Tavor series of rifles from Israel.
The bullpup, however, dates back much further with some argument to be made for the first firearms to utilise the concept being 19th century percussion target shooting rifles. The earliest military bullpups date to the beginning of the 20thth century, these include a rifles designed by Samuel McClean, the initial designer of the Lewis Gun, patented in 1896 (US #723706), by Major Philip Godsal (US #808282) and a carbine developed by James Baird Thorneycroft in 1901. Thorneycroft subsequently worked with Moubray Gore Farquhar and Arthur Henry Hill to patent a refined version of the carbine in 1905 (US #827893). While the Thorneycroft was tested by the British army it was rejected due to ergonomic and reliability shortcomings.
William Curtis’ design, however, predates all of these. Patented in Britain on 10th July, 1866, Curtis is listed by the London Gazette as a Civil Engineer. His design is unlike anything that had been seen before. Based on a slide-action with a drum magazine, it was placed over the shoulder – much like a modern shoulder-fired anti-tank weapon.
Curtis’ rifle is probably the very first bullpup magazine rifle, one of the earliest to have a drum magazine (an Italian, Marco Antonio Francois Mennons, patented an earlier design for a drum magazine in March 1862, GB #637) and also an early striker-fired design. Clearly a design well ahead of its time and radically unconventional.
This unconventional gun’s designer was born in Islington, London in 1802, as a civil engineer he worked on Britain’s rapidly growing railway network. He died in 1875, placing the development of his rifle nearer the end of his life. With hindsight Curtis’ design clearly had revolutionary potential but it appears that his concept was never taken up. It appears that he only patented his design in the United Kingdom. If not for a corporate lawsuit on another continent, decades later, then it is possible Curtis’ design, like so many others, would have slipped into historical obscurity.
Francis Bannerman vs. the Winchester Repeating Arms Company
In 1890, Francis Bannerman VI, a successful entrepreneur specialising in junk, scrap and later surplus, purchased the Spencer Arms Company and the rights to their patents. The company had been founded by Christopher Miner Spencer, designer of the Spencer Rifle, they produced the first commercially successful slide or pump-action shotgun. This pump action shotgun was designed by Spencer and Sylvester H. Roper and patented in April, 1882 (US #255894). Bannerman continued producing the shotgun as the Bannerman Model 1890, however, in 1893 the Winchester Repeating Arms Company, introduced the John Browning-designed Model 1893 pump shotgun (US #441,390).
In response in October 1894, Bannerman filed a law suit against the Winchester Repeating Arms Company claiming that the slide/pump actions used by Winchester’s Model 1890 and new Model 1893 shotgun infringed on the patents that he owned.
He called for the court to force Winchester to halt production and claimed $10,000 in damages and royalties for the sale of guns which he believed infringed his patent. Winchester temporarily halted production of the Model 1893, in the meantime Bannerman continued producing and improving his shotgun introducing the 1894 and 1896 models.
Various contemporary newspaper reports suggest between 100,000 and 500,000 people were directly interested in the case as ordinary owners were liable under the conditions of Bannerman’s suit.
Winchester dispatched George D. Seymour to Europe to scour the French and British patent archives for any patents for similar actions that had been filed there before those now owned by Bannerman. Winchester discovered four patents: three British and one French. The earliest of these was Alexander Bain’s patent of 1854. Two more patents held by Joseph Curtis and William Krutzsch were found, dating from 1866. The later French patent was filed by M.M. Magot in 1880. All of these designs, including the Curtis we are examining here, never progressed beyond the development stage and were largely forgotten until rediscovered by Winchester.
Winchester claimed that these earlier designs invalidated Bannerman’s patent claims. To illustrate their defence Winchester decided to build working models of each of the designs, breathing life into long forgotten patent drawings. This must have been a major engineering task as the patent designs would not have had all the information needed to produce a working model.
In 1895-96 Winchester engineers, including T.C. Johnson, assembled working models of each of the designs to prove their viability. These were tested and Winchester’s lawyers took them into court and submitted them as evidence, even offering a firing demonstration. The court declined the demonstration and made its decision on June 27th 1897. Judge Hoyt H. Wheeler of the United States District Court for the Southern District of New York ruled in favour of Winchester and threw out Bannerman’s suit.
Winchester had produced some 34,000 Model 1893s before, in November 1897, they introduced the improved Model 1897 which proved to be hugely popular on both the civilian and military markets. Bannerman unveiled a final shotgun, the Model 1900, but production ended in the early 1900s.
Curtis’ Unconventional Design
Curtis’ design encapsulates a number of features which, in 1866, were unheard of and arguably revolutionary. Not only is it probably the first magazine-fed repeating bullpup but it also uses a drum magazine, something that would not see substantial military use until the First World War. It has a folding shoulder support or stock, uses a striker fired action and makes use of self-contained ammunition.
The Curtis’ rifle is placed over the top of the user’s shoulder with a folding leather strap which fits into the shoulder pocket. Curtis’ original patent also suggests a fixed hook and strap. The user then grasps the loop near the muzzle with their support hand and the trigger and bolt handle with their other hand. Novel, but not the most ergonomic of designs.
The magazine appears to hold at least 13 or more rounds according to the available patent and Winchester’s engineering drawings. The magazine is fixed in place and rounds appear to have been fed into it through the loading/ejection port on the left side of the weapon. This would have also put spent cases being ejected right next to the user’s neck. Curtis’ patent explains that the magazine has a spring inside which has a length of string attached to the top of it which the user can pull back to depress it and allow cartridges to be loaded into the drum. The magazine has a single stack or loop of cartridges. Once loaded the string can be released, allowing the magazine spring to push rounds into the action.
The Curtis rifle’s action appears to lock at the front of the weapon with the bolt handle acting on a hinged, spring-loaded, locking piece or flapper which dropped into place when locked. To unlock the action the bolt handle was sharply pulled to the rear which pushed the locking piece out of engagement and unlocked the action allowing the operating rod to be cycled.
The weapon’s chamber appears to be just forward of the centre of the drum magazine with the striker assembly located behind it. To operate Curtis’ rifle the magazine was loaded and then the user had to unlock the action by pulling the bolt handle backwards. This then allowed the operating rod to be pulled backwards, like a pump action, which pushed the bolt and striker assembly to the rear, cocking the striker, the bolt handle was then returned forward and locked back into position. This chambered a round ready to be fired.
The trigger at the front of the firearm is connected to the striker assembly by a long length of wire. When pulled the wire becomes taught and trips a sear to release the striker, firing the weapon.
Originally Curtis’ patent describes how ‘small punches’ on the bolt face would pierce the cartridge base during firing to enable the spent case to be extracted once the action was cycled. From Winchester’s engineering drawings, however, it appears they replaced this with a more reliable and conventional extractor at the 7 o’clock position of the bolt face.
Given that the weapon would have fired black powder cartridges it is unclear how well the rifle would have faired with sustained firing. The drum magazine would have been susceptible to jamming as a result of powder fouling. This, however, would not have been an issue for Winchester later version of the rifle.
But the Curtis has one more interesting surprise. The original 1866 patent also includes what might be one of the earliest descriptions of a gas operated firearm. One of the most fascinating sections of Curtis’ original patent details how the rifle might have been adapted for gas operation:
“An arrangement is shown in Fig.10, in which the rod G is dispensed with; in this case the barrel may be shorter, not projecting beyond the shoulder; the butt is similar. The breech may be opened automatically by the powder gases, which pass by an opening in the barrel to a cylinder with which works a breech operating plunger.”
Curtis does not go into further detail but he is clearly describing a piston-driven, gas operated system. The patent drawing also depicts an alternative tube magazine instead of the drum magazine.
It is unknown if Curtis ever put his theory to the test and developed his gas system idea further. It is tempting to wonder if, in 1895 when Winchester were assembling their model of the Curtis, if John Browning or William Mason, who were also developing their own gas operated systems at the time, were aware of Curtis’ idea from 30 years earlier. As such Curtis’, admittedly vague, gas system pre-dates the first patents on gas operation by just under 20 years.

Thanks also to David Minshall of Research Press.co.uk for his assistance finding Curtis’ original British patent abridgement and to John Walter for digging up some additional information about Curtis’ life.

During my recent research trip to the US I was lucky enough to handle and examine a lot of very interesting firearms. This short video is a bonus, while we were opening one of the cases at the Cody Firearms Museum to examine another firearm (that video is coming soon) I noticed a sectioned British Pattern 14 rifle, made by Winchester for the British government during the First World War. It was too good an opportunity to pass up so I filmed this quick video taking a look at the P14’s internals.
The P14 would go on to be the basis of the US M1917 rifle built by Winchester, Remington and Eddystone.
The cutaway shows the internals of the rifle’s actions as well as the barrel, chamber and magazine. It was cool to see a cutaway of the P14 up close and I couldn’t resist grabbing some footage.
My thanks to the Cody Firearms Museum, at the Buffalo Bill Center of the West, for allowing me access to their collection. You can find out more about the CFM here.
