Lars, thanks very much for the very interesting information.
Your logic about the number of 95's possible in Finland seems right. I wonder if you are correct about the issue of 95's in the border areas. The Czarist Armies were issued many different rifles, and it would make sense that they would be issued to units in a single theater, or region in order to minimize logistical problems.
I wonder why the 3611 95's were in Finland, that is, what units were issued them, or...did they merely wind up in Finland after the breakup of the Empire?
