Godsal 1918 Anti-Tank Rifle
While the Imperial German Army’s T-Gewehr is relatively well know, it’s short-lived British counterpart is almost unknown. The Godsal Anti-Tank rifle, developed in 1918, represents an answer to a problem Britain did not yet face.
The name Philip Thomas Godsal is more frequently associated with another unusual firearm - the Godsal bullpup rifle developed in the early 1900s. Major Godsal was a British army officer, who joined the 52nd Light Infantry in 1869, eventually leaving the army in 1880. He became a well-known and respected rifle marksman winning a number of prestigious shooting competitions.
By 1918, it appears that working with Webley & Scott, who had also built his earlier bullpup prototypes, Godsal developed a bolt action rifle chambered in a large .5 inch calibre, perhaps as a response to the German T-Gewehr. At the time the rifle was being developed Godsal would have been around 68. It is unclear if the development of the rifle was a project requested or sanctioned by the British government or if it was a private commercial venture to be offered to the military when complete.
This rifle in particular is marked ‘1′ on its receiver and proof marked near its trunion with ‘.600/ 500′ referring to the British .600/500in round used in the early .5-inch aircraft Vickers machine guns before the switch to 12.7x81mm. The version of the round used with the Godsal used a bullet with a soft lead core.
The action seen in the photographs of the rifle held by the Royal Armouries’ collection bears a strong resemblance to an action patented by Godsal, in the US and UK, in 1914. It would seem that Godsal was able to scale up this action for use in a rifle chambered in a much larger cartridge.

The action appears to be a development of the one developed for use with his earlier bullpup rifles. In the anti-tank rifle the pistol grip and trigger have been moved back to a more conventional position and the anti tank rifle does not have a magazine and is likely a single shot weapon, much like its German counterpart. The prototype has a rather thin looking pistol grip made from a machined metal piece that extends from beneath the action, making up the the trigger guard and then projecting back down the wrist of the stock. This was no doubt to strengthen the wooden stock. The pistol grip itself has wooden panels held in place by a pair of screws. The buttstock looks to have a half inch thick butt pad, possible made from rubber, to aid with recoil.
The rifle’s sights are marked from 2 to 20, probably indicating a graduated range of up to 2,000 yards. The weapon has an exposed, dovetailed front sight. Interestingly, the early .55 Boys Anti-Tank rifles, developed in the 1930s and eventually adopted by the British Army, had an almost identical muzzlebreak to the Godsal rifle.
The prototype appears to have a very large extractor on top of the bolt, held in place in a dovetail. Simpler but somewhat similar to that seen in the 1914 patent. Additionally corresponding to the patent is the location of what looks to be a safety catch on the right, top, side of the receiver. There are also signs that changes have been made to the prototype during development such as a scallop cut in the stock and receiver on the left, an exposed, empty slot and a number of holes drilled into the receiver. There is no sign of any wooden handguards being attached to the rifle and it likely used a bipod or a rest for testing.

It is likely that development of Godsal’s came to a halt when the First World War ended. With little money available for military research and development and no urgent need for an anti-tank rifle the project was probably shelved in early 1919. Godsal’s anti-tank rifle certainly intriguing and deserves to have its story investigated further. Godsal died in 1925, aged 75.
