DWM Luger

Hello,


I am wondering what is the manufacturing year of the Luger that I just got. It is a DWM Commercial 9 mm luger with 4 " barrel. In the side of the gun and under the barrel there is commercial proof mark N with crown (sheet 1 mark 4 in Technical Information)


The serial number is 74431 and it is stamped in the barrel and in the front of the frame. Several parts are stamped with number 31.


The gun has a light brown holster with the year 1915 in side also marking J.R.111 which might indicate to infantry regiment 111 (in Finland). There is one magazine with wooden bottom plate and no number.


Thank you


Tero
