Thanks for the replies guys, it sounds like I got a fairly good deal on that Luger.
John, here is a pic of the inside of the left grip. It isn't the best photo that I have ever done, but it is the best that I could do, under the circumstanses.
The inside of the left grip
The other Luger was an all matching numbers, (except for the magazine), 1940 Mauser, in very good, almost too good condition.
It had brown plastic grips.....hummmm.
He wanted to keep that one though.
