Rifle is a Greek Return purchased from CMP. SN 4004498. Rifle is in mint condition and is all Remington with exception of the bolt sleeve which is Smith Corona. Also has RIA stamp on the left side of the stock with letters EB. Question is: Did Remington use Smith Corona parts during production. Rifle does not appear to have any troop use. Muzzle is perfect and I believe barrel is org. Dated 9-43. I am assuming rifle was processed through RIA prior to sending to the Greeks. Finish is as issued to include the bolt sleeve. A two groove tack driver. Thanks for any help...
