Hi Tyler, Welcome to the forum! You have a very collectible 1914 model, 1916 dated Navy Luger. In addition to the marks you mention, the barrel and left side of the breech block should also be stamped with Navy crowns, and the front sight base should be stamped 1916. I maintain a data base of all known Navy Lugers and would like to add yours to the list. You can post the serial number here or send me an email if you prefer. Regards, Norm
