Newbie Introduction and 1937 S-42 pics

[Sapper]

Greetings All,

I wanted to stop in and introduce myself and show off my 1937 S-42. I'm from NE Penna, former military and a casual collector of military firearms. I've spent the last few years working with AK-style rifles and shotguns, and I've only recently rediscovered my first acquisition (see pics below). Anyway, I'd like to say thanks to everyone for all the great information I've gotten from this site!

My photos aren't very good, but if anyone can pitch in with a little info about my pistol I'd really appreciate it. I'll eventually pass it down to my son so it's not for sale, but I'd be interested to know what it's worth if anyone wants to throw out some numbers. I've got a bunch more photos I'd like to post so please wait until I've uploaded them all before replying. Sincere thanks in advance!

Details:

1937 S-42 Mauser P-08
Serial 7461"r" with tons of Waffenstamps
All matching numbers (AFAIK)
Black plastic grips (original?)
Non-matching period magazine (5715"g")
Finish not so good (%?)
Fed and fired flawlessly until the Hold-Open Latch Spring broke
Anyone know where I can find another spring?

Warm regards,

Sapper
