There is a Finnish-made version of the Russian stock. It is lighter birch wood and has slightly different profiles. Harder still to find than a more typical Russian rifle picked up off a snowy battlefield.
What colour is the bolt carrier? For an old import piece, it should be unfinnished (get it? Finnished?).
If my sequencing is correct there were several waves of imports.
The last batches have plum red bolt carriers. A dead giveaway. These are the most numerous, and have the widest variety of makers, years, and variations. Everything has electric pencil scribbled numbers.
The next to last group came in the 90's. Mine came through Jose Reis with G5 Imports (?) on the south shore of Montreal. It was refinished with modern bluing, and German proof house marks were laser engraved in places.
There was a long drought to the next batch. In my opinion, this is when the Finnish capture rifles came to Canada. These have SA marks, are often in rack-grade surplus condition, and often in poor overall shape than the later batches. If the chronology is right, they arrived when 7.62x54R ammunition simply wasn't being sold by the Soviets and anything else was pricey as heck. For that reason, a company in Vanier (Ottawa) calling themselves Globe Firearms converted large numbers of SVTs to .303 British, shortened the front ends, and sold them as Mohawks. Just about as pathetic a conversion as conceivable. They put the chop on everything they bought, trying to make a living when no one was buying rifles they couldn't shoot.
FWIW, Americans cannot buy SVT rifles. So ours are cause for real border envy.
