Info on this c.v. h would be much appreciated. I have a mk 31 also what I believe is a "newer" regular c.v. h . This new find has me curious.the scales are ivory and seem to be original. No washers at the pin. Seems to be a 4/8 hollow. The only I d is the c.v.h and eskilstuna on tang and etching on blade. Thanks in advance. I'm guessing 1920's.? Thanks
