Its likely a Lend Lease Garand....look for Brit proof marks BNP at front of receiver and the side of the Barrel.
These Lend Lease Garands were in that serial number range and the Brits " sporterized " them after the war...checkered stocks, nip the barrel down a bit, uncut oprods etc...
They can make good parts donors if the barrels are not nipped as they are usually really nice '41/'42 dated and the sights are usually period correct early with early bolts and trigger groups....not in US service so they did not get the armourer upgrades to newer parts.\Cheers Paul
