1941 Military Luger by Mauser? (Pic heavy)

[Timah!]

I am a new collector and have decided to take the plunge and purchace my first. I'm not too sure what I have and any insight is much appreciated. I have a few concerns... The first is the serial number on the left receiver. At first glance, it appears to read 3301. Upon further inspection the 0 seems to be a stamped over to cover another 1. Perhaps the original serial number was 3311? My second concern is the font of the silver piece on the left side. It LOOKS like 02 but if you look closely, it is infact 01 but the font of the 1 (looks like a stubbier version of this 1 font) is different from the other 1s which have the subtle hook at the top and a verticle and widening down stroke. My third concern is the other serial numbers. 34 appears multiple times. I believe I read in the FAQ section a while back that it was not uncommon for some of the serial numbers to be a digit up from the first two numbers of the original (ex. 3301 having 34 on some of the matching parts). I read recently in the FAQ that all military Lugers have the last two digits only. My final question is the overall condition and desireability (if that's a word) of the piece. I have a holster (minus the tool) for it which I deem to be in very good to excelent condition (but what do I know?). Also, I have two magazines serial numbered 8797 and 9290 both with various stamps which both include the stick-figure eagle. I have included many pictures and can aways take more if closer inspection is needed.
