Is it common to see Russian-Soviet parts mixed in with Finnish made Mosin Nagants?
Yes this is very common to see. In most cases the Finns used every Russian part they could make use of. It is not uncommon to see a large mix of parts in a Finnish rifle. This is very common in the bolts as a number of maker stamps can be located on the same bolt. In some regard the Finnish Mosin Nagants are parts rifles, but they are the ultimate in parts rifles. The Finns were masters at taking what they had an improving it.
