One of these things is not like the other

Hey:

I am new to the forums, as well as the Luger world. I just got my first luger a few days ago and I have a few questions that I am sure you guys could help with. My luger is a 1916 DWM nearly all matching, with the exception of the sideplate.

As you can see, my sideplate is neither numbered nor is it the same configuration as a normal luger sideplate. The dealer i bought it off of had never seen something like this before. My guess is that it is either a machined part or it came from another countrie's luger knockoff. I dont have anything to backup my ideas.

Anyone ever see this before, or know what it is?

Thanks!
