Was that M44 a Polish (11) ?
It looked like one in the first pic.
And a matching number Polish M44 is as rare as a REAL intact PU sniper 5/10 with the exception of the 1951 Polish M44 which is even more rare at 8/10.
"Rarity" that interest collectors are year of production, location of production, and ancillary markings. For example, 1943 dated Izhevsk M44s are difficult to find while 1944 dated Izhevsk M44s are readily available from numerous distributors. Change the arsenal to Tula, or add a DDR "triangle 1" mark to the same 1944 M44 and you have a sought after collectible.
