Post-war M91’s generally follow the pattern of the wartime models, aside from the barrel markings. In 1942, Finland purchased approximately 13,000 M91 barrel blanks from Belgium. These barrels are marked with a “B” and 1942, though some also have VKT firing proofs, Liege firing proofs and/or “D” chamber modification markings. It is not known why VKT did not assemble these barrels into rifles during the war, though it is possible the barrels may have been delivered after wartime M91 production ceased in 1943. Arms production restrictions forced upon Finland by the cease-fire terms of the Continuation War are the likely reason why the B barrels were assembled into M91’s using spare receivers and/or damaged earlier rifles as a source of actions and parts. It is not know what year these rifles were made, but all B barrel rifles were assembled post-war despite the 1942 barrel markings. It is believed only about 4000 to 5000 B barrel M91’s were produced. The remaining barrels were than reconfigured and used to assemble M39 rifles.
