Hi George! And welcome
You've come to the right place for learning more about Lugers of all types.... the experts here have a wealth of knowledge and experience second to none. Only thing I would add to the above is to take your time looking, enjoy the process and the search, ask questions, and, if possible, post photos here of a gun you are thinking about before you "take the plunge." There is a wealth of YouTube videos available, and many posts and threads here which have lots of Know-how and valuable information.
A general price range for a reliable shooter with minimal pitting and finish issues would be between $700 and $1000. (I assume a shooter to be reblued with this comment on finish.) Please, experts out there, correct me if needed!
Hope to hear from you soon!
