First glance says it’s a DWM commercial Luger, looks like a pre-war one since the barrel appears to be 4 5/8” long. Would need more pictures, especially those of any/all proof marks and serial numbers. Which will be located on the trigger guard on the front of the frame, underneath the side plate and takedown lever, underside of the barrel, and on the toggle links for sure. They might also be on the toggle link pin in the rear, firing pin, and the inside of the grips among other places, but some examples are also left unmarked and this is considered normal. I am sure that one of the moderators will post a link to it, but all of us would recommend you read the FAQ document that can be found as one of the tabs of the home page to help answer questions. Several YouTube videos also show how to properly disassemble your Luger to check for proofs and serial numbers, but if you are uncomfortable do this yourself, take it to a gunsmith who does know how to do so without damaging it.

Side note, there doesn’t seem to be a pin that should go down through the left toggle knob and that looks like an empty hole, not sure I’ve seen that before and I don’t know what, if any, problems that may cause. Merry Christmas to you and congrats on your new acquisition.
