Yes, it is a Crosman M1 carbine same action as the model 350 which was the fps which it was rated for. There were 2 versions, 1966-67 with a wooden stock 1968-76 with plastic Crosman called it "Croswood" stock. I believe within the plastic stocks there was also a darker and lighter version but I don't know too much about it beyond that. Mine has the wood stock original magazine, owners manual, and factory service manual too.
