just ran into a web site called Jager Platoon when researching Finn M39s
has some good data on Mosin sniper rifles that I've not seen before
the data on eye relieve for the Mosin sniper scope was good data for my PEM build out.http://www.jaegerplatoon.net/RIFLES7.htm
as noted on this web site, most captured Mosin sniper rifles were sent home by Finn troops and never turned over to the Finn Army.
the were very prized by Finns as hunting rifles
