I have an M-91, NEW, stock has NEW cartouche, barrel & reciever are NEW, bolt & bands are Izhevsk, SSE's & wire hangers are Finn. There are a couple of other circle cartouches on the stock I can't really make out. One looks kind of like a "Y" in a circle. So does anybody know why this thing would have the Finn hangers on it? Did Finland get any of these? Thanks for any help.
