What letter blocks are these three rifles? Does the first 1943 have any acceptance on the left side of the barrel?
Here are the diamond proofs from two 1946 M44s. The proofs on my '47 and '45 non-refurb M44s aren't legible:2) In 1945, an additional inspection was added to the stock. Its a large diamond with what I think is "жЕС1" (not sure of first letter, other numbers may be possible). This stamp is found on all stocks from 1945 until the end of production, so we know that the stock pictured below is from early/mid 1945 (no liners, ОГ inspection) and not 1943.
The CCCP roundel was not in use until 1937, so someone replaced the stock with a nicer 1940/1941 stock, probably from a Finnish import, after its arrival in the US.I have an ex-Ejército Popular Spanish Civil War Izhevsk 1933-dated 1891/30, barrel and buttplate/stock serial numbers matching, that has the (пп) marking and the hammer-and-sickle CCCP cartouche/emblem.
