2/17/20 - This is an early magazine for the Nazi era Femaru M37 in good condition overall. It is marked Model 37 on the bottom of the magazine and serial numbered as well. This would go with a Nazi Femaru JHV41. It is made for 7.65mm or .32 caliber. It has a blued finish with lots of brown patina and areas of wear throughout. The spring seems to work fine.
