Our specs are the same-- I believe these to be what I would call 2A1 modified carbines. Numbers matching with the exception of the muzzle nose piece and mag. I received 2 mags-- 1 aftermarket and one original 12 rnd mag.. I had to beat and bang on the aftermarket to get it feeding correctly and it had never been disassembled. It had been epoxy'd like John Sukey's. Mebbe it was his. The clincher for me was the blood stained sling that came with it. I'm new to old rifle gig. Fool born in 1943.
