When I purchased an 1936 s42 last week, I also was given a "carbine shoulder stock". There were no markings or stamps on the wood stock or the metal lug. The "release/locking tab"? has half the "tab" broken off, but the hardware works. I have attached photo's for you folks to look at. Opinions are greatly appreciated!!
