M/19 Fiskars
Reference photo from Arma Fennica 3.
These photos were sent to finnish mag Antiikki & Design for idenfication and value estimation. Belt hanger could be same as AF3 ref pic.
Photo from some russian dudes collection. Modified? guard.
Really not lot of data about this model. Some observations:
-German manufactures copied this design, so either there are 2 official guard patterns or soldiers modified it.
-All belt hangers look different. AF3 and A&D could same, my #2 looks similar to german ones and uses loop in scabbard. Two patterns?
-Maybe 2 options: long guard and wide frog, short guard and loop hanger?
