Help please

[m135976]

First off let me say this is my first post and I am new to what appears to be a very passionate hobby, so I would appreciate your patience and understanding. While I shall continue to do my own independent research I would appreciate any help the forum at large can offer.

The Story:

My grandfather in Europe during WWII managed to obtain a German Rifle, on the boat back to the U.S. he met up with another GI who obtained a Luger in a similar fashion. The man being a hunter decided he had use for a rifle rather then a pistol and traded it to my grandfather. Obviously it became an heirloom of sorts and was given to my father after my grandfather passed away from a heart attack. Unfortunately our house was burglarized a few years ago and the Luger was among the things taken, far more valuable then any of the stereo equipment also taken.

I would like to see what it would take to obtain a replacement. While it may not have the same sentimental value I would at least like to explore the option and see what is possible.

Unbeknowst to me was how many different models there are. I believe I have identified it based on observation only, It is the second one from the bottom but I can not quite read the exact model number

My questions for the forum experts are as follows:

What kind of Luger is the one I managed to identify?
What would the cost of an authentic replacement run? (assuming it is in realitivly good condition?)
