Desi Sten 9mm tamancha auto

American make Desi Sten

“Sent in to TFB is another concept design for an ‘afternoon’ DIY submachine gun of particular crudeness and expediency. The majority of components are laminated together from readily available square section steel tubing, owing to its namesake. Apparently the only thing that cost anything was the STEN mag and compression spring. The model shown is a non-firing mock-up dummy for the purposes of demonstration only.” The Firearm Blog

32 bore desi katta gun pistol

Here is a simple little semi auto pistol design sent in that will likely be of interest:

“A homemade conventional type self-loading pistol need not be complex in design or demanding in tools needed for it’s construction. Here is a bare-bones pistol design which is constructed from sheet steel and bar stock, the only power tools used to make it being a drill, angle grinder and a welder.”  The Firearm Blog

Winchester Liberator



An excellent video on the Liberator series of Winchester shotguns from Forgotten Weapons.

“In the early 1960s, an influential but little-known (today) firearms designer by the name of Robert Hillberg came up with an idea for a cheap-but-effective armament for the masses. With encouragement from DARPA, the Winchester company took up manufacture and development of the design, under the name “Liberator”.

The guns were initially planned to be made almost entirely as magnesium castings, with steel liners in the barrels, with a total cost of about $20 per gun. They would use prepackaged 4-round ammunition packets as well, rather than standard individual shotgun shells. By the time production was actually begun, however, the design had been altered to a break-action system using regular shells – the prepackaged quad-cartridges proved too difficult to perfect. So the production Mark II guns used conventional shells with a break-open action.

As it turned out, casting the frames over the steel barrel inserts was a quite difficult process, and Winchester soon moved to a MkIII design which replace the barrel casting with 4 independent all-steel barrels fixed at the muzzles by a stamped plate. By this time, however, military interest in the guns had fallen away and Winchester was left to try to market them commercially. They attempted to interest both police and civilian markets (although with 13 inch barrels, the guns were regulated by the NFA). None of these marketing attempts succeeded, and major production never began. The design was too impractical and guerrilla-oriented to really appeal to anyone with a more ordinary use (like recreational shooting, sport shooting, or security/law enforcement) in mind.

Thanks to the Cody Firearms Museum for allowing me access to film these!”

Enfield Revolver No.2 Mk.1 .380


Type: Revolver, Double Action
Chamber: .455 British service; .38/200 (.38S&W)
Weight unloaded: 995 g (Mark 1 – Mark 5 with 4 inch barrel); 1100 g (Mark 6)
Length: 260 mm (Mark 1 – Mark 5 with 4 inch barrel); 286 mm (Mark 6 with 6 inch barrel)
Barrel length: 4 inch (101 mm) Mark 1 – Mark 5; 125 mm (some Mark 3 and Mark 4); 152 mm (Mark 6)
Capacity: 6 rounds


The first top-break revolvers were developed by the Webley & Son company (Webley & Scott Co. since 1897) of Great Britain in the 1870s. First Webley revolver had been officially adopted for Royal Army & navy service in 1887, as a Webley Revolver, .455, Mark I. It was a break-top, six shoot, double action revolver, chambered for blackpowder .455 British Service cartridge, officially known as Cartridge .455 revolver, Mark I. This cartridge launched heavy, 18 gramms (265 grains) lead bullet at relatively slow muzzle velocity of 180 meters/second (ca. 600 fps). Later, smokeless version of this cartridge had been adopted, but since it also could be fired in early revolvers, the gain in the velocity or muzzle energy was very minor.

All Webley top-beak revolvers featured two piece frame, which hinges (“breaks”) down at the forward low end for ejection and loading. The ejector is actuated automaticayy when the frame is broken open, simulateonusly removing all six cases from the cylinder. The cartridges then can be inserted by hand. In the case of revolver being rechambered for .45ACP round, half-moon clips are used to load the gun (two clips, each for 3 rounds). All Webley revolvers were Double Action or Double Action Only, with very distinguishable shape of the barrel and frame lock with lock lever on the left side of the frame and V-shaped lock spring at the right side. Below is the list of all Webley revolvers, officially adopted in Great Britain. Many other variations were also manufactured for civilian and police use.

Webley revolver, .455, Mark 1. Adopted in 1887, chambered for blackpowder cartridge. 4 inch (101 mm) barrel, “bird head” shaped grip.

Webley revolver, .455, Mark 2. Adopted in 1894, almost the same as Mark 1, but hardened removable steel blate was added at the back of the frame breech, hammer was strenghtened, grip was slightly rounded.

Webley revolver, .455, Mark 3. Adopted in 1897, this was Mark 2 with improved cylinder to frame lock. Cylinder can be removed for cleaning. Since 1905, some Mark 3 revolvers were also made with 5 inch (125 mm) barrels.

Webley revolver, .455, Mark 4. Adopted in 1899, this was an improved Mark 3, made from different steel, with smaller and lighter hammer and wider cylinder slots. Since 1905, some Mark 4 revolvers were also made with 5 inch (125 mm) barrels.

Webley revolver, .455, Mark 5. Adopted in 1913. Mark 5 was designed to accept smokeless (cordite) ammunition, and thus, had larger and stronger cylinder, and accordingly redesigned frame.

Webley revolver, .455, Mark 6. Adopted in 1915, it was the “ultimate” Webley .455 six-shooter. Mark 6 featured redesigned, more squared grip, 6 inch (152 mm) barrels, removable front sights. Mark 6 revolvers were manufactured by Webley & Scott until 1921, later these were manufactured by Royal Small Arms Factory at Enfield Lock. Oficially rendered obsolete in 1932 with the adoption of the Enfield No.2 .38 caliber revolvers, but widely used by British troops during the World War Two.

Webley revolver, .38, Mark 4. Oficially adopted for military service in 1942, this was initially a scaled-down version of the .455 Mark 6 revolver, chambered for .38 S&W cartridge, and developed by Webley & Scott in 1923 for police use. These guns were oficially regarded obsolete as late as in 1963. It should be noted, that oficial british .38/200 ammunition was based on early, blackpowder .38 Smith & Wesson cartridge, and was used with heavy 200 grains (13.4 gramms) bullet, leaving the muzzle at relatively slow velocities of about 198 meters/sec (650 fps).
