Hi, and welcome to the forum.
Are you in need of information about your Luger?
From what I can see, it is a 1915 in original finish. On top there should be either the ornate letters "DWM" or the name "Erfurt" under a crown.
Some better photographs that are more in focus will be needed to tell you much about your gun. Take them out of doors in indirect sunlight and don't use the flash.
Marc
