What are marking on this DWM

[3598]

I will post some more pics. Sorry about the quality Im using my new I-phone 5.
It should also be noted that it is a single digit serial number. The serial number is marked on barrel, frame, side plate and toggle bolt behind rear sight. The side plate and takedown lever are also marked with serial number but only visible if pistol is looked at upside down. Extractor is in german language. Matching serial numbered mag with same proof mark (V with the dot). I removed the left grip, correct serial number with same V marking.

The single digit serial number has no script letter.

Im really stumped on this one. I have googled searched every possible combination with no luck.

Thanks guys

I've taken another look at the pictures posted so far, and it's not only the markings that are odd. As you can see in the photo below, the rear face of the sear bar slopes backwards, it should slope forward so that it can engage the safety bar. Grip safety guns have sear bars that slope backwards, but their safety bars slope backwards too.
