You need to do some research. Genuine M1C rifles were within a fairly specific serial number range. The scope mounts would also usually have the rifle's serial number on it with an electric pencil. If the rifle is out of the serial number range then most likely it's made up by someone later. The 1952 date barrel is likely an arsenal replacement.
Genuine M1C rifles bring substantial money but for top value it needs to have provenance...usually a DCM sales invoice.
