German WWII Kriegsmarine Protractor Plotting Device-This is a large instrument which is approx. 34” in length. It is a sophisticated plotting device used by navigators aboard Kriegsmarine ships. This is marked not only with the German eagle but is also stamped M 1240 along with the maker’s code which is cln. This comes from a very old, advanced collection and is reputed to be off of Hitler’s Yacht, which was the Aviso Grille. However, I was unable to find any additional documentation, so I am selling the item and not the pedigree. This is desirable in itself. Near excellent condition!
