1937 Marked S/42 Just Purchased Please Review and Comment

[Lugermeister]

Well, I've waited a long time to purchase my first Luger. The one in the pictures attached is a 1937 marked S/42. I just took it out of the box, along with four other Mauser Pocket Pistols I purchased from an elderly gentleman in his 80's. He's had these 5 guns and many more, for 40 plus years. I'll post a picture of the 5 and then pics of the Luger, for which I would like some help.

I searched here http://www.lugerforum.com/index.html, but still need some help. Even with my magnifying glass, some of the symbols etc were hard for me to see.

A few pictures to start, as my picture size is too large I guess. I'll reply to the post with more pictures.

I look forward to comments, thoughts and a good education.

Thanks all in advance for helping me out.
