DWM Commercial .30 Year/Value

[kol]

Hello, a month or two ago, I purchased a DWM commercial Luger in .30 Luger. I am interested in finding out a year of production and an approximate value. 'Germany' marking on left side of the frame, serial number is 8127, and there is a script 'O' under the barrel and what looks like an 'N' on the frame. I can take more pictures if needed.
