|While Finland entered the winter War with more M-91s than
any other rifle, by the Continuation war, the M-39 had replaced the M-91
as the most common Finnish rifle. There was a good reason for that
transformation. The M-39 is generally regarded as the most advanced
Mosin Nagant including those from Russia and all other countries that
produced Mosin Nagants.
It was the product of a design team made up members of the Civil Guard and Army. Of the two finalist rifles submitted, the Civil Guard version emerged victorious.
The M-39 had as high a percentage of Finnish designed and manufactured parts as any Mosin Nagant produced. In fact, the only Russian parts used in producing M-39s were the receiver, magazine, bolt, portions of the trigger assembly, and butt plate.
While M-39s were produced with both Army and Civil Guard markings, they were essentially the same rifle. When it came time to replenish the Finnish arsenals after the Continuation War, the majority of rifles produced were M-39s.
There is sufficient variety in M-39s to support their own branch on the Finnish Mosin Family Tree. For example, a limited number of SAKO M-39s were produced with straight stocks.
A variety of barrel markings can be found from four different barrel manufacturers including the Belgian B barrels.
Then there is the mysterious 48
And even a barrel with no manufacturer name and no date.
There are a number of interesting and in some cases apparently conflicting combinations of barrels, stocks, receivers, and condition . Take the time to explore the rifles found under the leaf symbol in the left column.
