Fede iam inclined to aggree.the two examples you show are similar and the name is the same . the second photo shows a rifle descibed elswere as the kretz rifle useing a coil spring in the but hooked to a chain that operates the bolt.
Agreed Fede. This was based on the Pattern ’13 rifle in .276 inch calibre. It was part of the British semi-auto rifle trials that took place 1909-1914.
I have the weapon drawings and photographs. It has a blow forward gas trap at the muzzle like a Bang.
An example exists in the Imperial War Museum collection in London.
I should have said in my previous post that the calibre was not .276 inch Pederson as mentioned by Fede but .276 inch Enfield, a much larger and more powerful round intended for the Pattern ’13 rifle. The Pederson had not been developed at the time this rifle was made.
Thedesign is too bad. sort barrel and magazine is too frontward
