Re: Any M1 Garand experts here?
It looks like you have a Feb. of 1944 receiver with the correct trigger housing and stock. If I am reading the barrel right, its a Dec. 1948. The receiver and trigger housing look to have been re-parked and the parkerizing is pretty thin. It probably went through a re-arsenal and you might find some electro pencil markings on the right side of the receiver below the wood line. To check the op rod, the piston should measure at least .525" diam. To check the Gas Cylinder, you can take a belted magnum brass (7mm, 300 or 338 win mag)and see if it fits into the gas cylinder. If the belt on the brass fits into the cylinder over 1/2" its probably toast. You can also use a loaded M2 round and insert it into the muzzle and see how much of the bullet still shows. If it goes all the way to the brass, it needs to be re barreled. Also check to see if it has an import stamp on the barrel near the muzzle. From looking at your pics, your Garand looks to be a Field Grade = $500 at the CMP if the parts check out ok but its tough to tell without knowing how they gage.
Hope this helps, Mike.
