In 98% mint crisp condition we have a German WWII Kreigsmarine Eagle/M marked Model 1934 Mauser Pistol in 7.65mm (.32 auto). This is a variation 3 example with the Eagle/M Naval property mark on the right side of the Frame and the Nordsee Fleet property # on the front grip strap. This pistol is all matching and the bore is mint as well. Much nicer than you will usually find these pistols as many suffered extensive corrosion from the harsh salt water marine environment.
German Navy marked Pistols are heavily collected due to the large Nazi era markings and because of the romantic connotation of being a U-Boat Pistol. The Nazi era German Naval Service known as the Kriegsmarine was a much smaller organization than the army and they needed far fewer pistols. If you take this into consideration while also aware of the fact that most of the pistols are sitting on the bottom of the North Atlantic you will understand how rare and desirable these artifacts are today.
