DMW commercial year?

[Jtoon2b]

I am needing help identifying this commercial Luger. I believe it’s a new model 1908. It’s a 30 Mauser. All numbers matching except mag and safety bar. Also someone sanded off most of the grip lines off of the back strap. In looking I can’t find one with these lines which is odd. Any help would be great. I’ll try to include a good picture of the back strap.
