Hey Poot! Yep, there are a few SA M44s 43/44 is US collections however I would not call them "alot". I would have to look at my notes but I think Tuco or Vic stated a few years ago after a trip to Finland that there were only a couple hundred M44s captured. The Finns bundled the M38s and M44 into the same number as "carbines" and I think that number was only a couple of thousand. The M38 is a uncommon find as well.
I came into the 1943 SVT40 by absolute dumb luck. I have alway wondered how many of the late date 43-44 SVTs (Finn captured of course) were in collections today? Seems like Cruffler has one and I belive Vic has the entire line up-to 1944 (SA). Others?
