First Luger, Did I get hosed?

[Sgt. Shifty]

Hello Gentlemen!
New member here, looking for some info on the Luger he just bought at an auction! There is definitely a lot to take in here on your site and I am trying to learn on my own, however I am dying to know if I did "ok" buying my Luger.

It is a 1937 S/42 Mauser, and it came with a holster, two magazines (non matching), and capture papers. I have not taken it apart, but every number I can see from the outside is matching. The capture paper looks legit to me, and what I thought was cool is that the GI wrote his name in pencil inside the holster! One thing that kind of made me wonder is the blued mag, it has no serial number and looks to be in too good shape?

From what I have read so far, I am wondering if I gave too much for it....about $2k....a friend thought that was a good price but from what I have found so far I am not so sure. So, that's what brings me here!

Anything you could tell me about it, or an idea of it's value would be greatly appreciated! Thanks and a Merry Christmas to All!
