Luger identification

[mrerick]

Your Luger is made of a mix of parts from different eras. The grips and magazine are late WW-II (1941-1942). The crown/N marked receiver is a commercial gun's receiver. My guess is that it's from a very early DWM Luger because of the proof mark's position. The extractor looks to be from an Erfurt. The side plate and take down lever are numbered in the commercial style from different guns. Barrel looks replaced and perhaps aftermarket, or Finnish as mentioned by David.

Is something ground off the barrel above the import mark? If so, you might have a problem. I believe that CAI sometimes serial number marked their imports, and that could be a ground off serial number (which is illegal in the USA). Is there a serial number and suffix letter on the barrel, and on the front of the frame?

My guess is that you may have an early Finnish or Russian Capture import made up of parts from several guns.
