Here's a Luger being sold as commercial that has me a bit confused.

I don't see any proof marks at all. There is the serial number stamped on the frame above the side plate. The placement of the number on the take down lever and side plate are not correct for commercial, or am I mistaken?
It looks clean, but doesn't seem to be a commercial to me. Or have the usual military marks either. I'd appreciate it if someone could set me straight.
