At the time of the Russian revolution Finland was under the rule of the Tsar. When Nicholas II was deposed Finland declared its independence and defeated the Russian forces in Finland, but retained stores of arms. With an urgent need to build an army to defend itself from the real threat of Russia and many Mosins already on hand it only made sense to adopt it as the primary rifle. Between WWI and WWII Finland actively traded other types of rifles in their inventory with countries across Europe and Asia for Mosins which they had captured. The condition ranged from serviceable to “parts guns”. With an abundance of spare parts it was only natural to use them to build “new” rifles that could be put to use. From 1922 to 1924 Suomen Ampumataruikehdas made a small number of M91s marked SAT Riihimaki on the barrel shank. In 1925 Finland began production of barrels at Tikkakoski (Tikka) which were assembled into M91 configuration with dates of 1925, 1926, and 1927. The later 1926 and all 1927 barrels were a heavier type with a step near the muzzle to allow the use of the standard bayonet. During the Continuation War Finland also built many M91s with barrels made by Tikka and VKT.  Barrel blanks were also purchased from Belgium but were not assembled until post war and are known as "B barrels".

The rifle pictured at the top of the page is in typical early configuration with the stepped barrel, early barrel bands and Russian stock with sling slots. The rifle pictured below is in typical late configuration with a straight barrel, late barrel bands and Finnish two piece stock with sling swivels in escutcheons with round holes. However, Finnish M91s can be found with a mix of features on rifles of any age as there were no set standards, especially during later refurbishment.

Sight Variations
Finnish M91s have the same type sights as the Russian Konovalov design of 1908.  The primary difference is the Finns remarked the rear sight bases in meters utilizing the existing notches.  Occasionally an extra notch is cut at the rear of the base and is marked 2 (200 meters).  Typically the numbers are placed on the right side of the base which was left blank by the Russians, but there are lots of variations in the manner of the numbering and how the existing Russian numbers were treated.

Finnish M91 front sight bases are integral to the barrel and identical to the Russian version.  However, the variation in blades is tremendous.   Many of them are pictured below with brief descriptions.
