I've had mine for a lot of years and it's a 674XXXX with a barrel date of 1-45 and a hand stamped 1 on the receiver. It's all Inland and it has all the proper Inland parts and an I-O stock and handguard and the correct cartouches and late features, ie: low wood, flip safety and bayonet lug. Is it original? I have absolutely no clue as to th e answer. All I can say is it's certainly worth the $250 I paid for it all those years ago.
