Fred, I am sure the Luger collectors on this forum are willing to offer you help and are willing to answer any questions you may have. But you will have to give them more photos and info. We can even help you with posting your pictures
If you are not able to provide us with any info on markings proof marks ect, give us more photos. Maybe start by telling us the toggle inscriptions and chamber date (if there is one)? This will give us a basic idea of what type of luger this is.
Looks pretty nice from what I can see though (but there is so much more to it than that).
