DWM Commercial Luger Info

[WestPoint18A]

Hey guys,

I have had my DWM commercial Luger for quite some time now. It was given to me by my father and to him by my great grandfather. My great grandfather fought in WWI, and was a translator and interrogator. He said that he got this Luger from an officer who he was interrogating.

The serial number is 4204 k. It has the crown/n proofs, and has a Germany stamp on the front of the frame. I would like to know approximately when this luger was made, if that information could be found.

Thanks,
