Item Description
Original Item: Only One Available. Genuine rare WWII Bruning-Wallace Aircraft Mk.IIIB Navigational Drafting Protractor. The instrument is identical to the AN-5750 Protractor used by the U.S. Army Air Forces, but in this case was ordered by the U.S. Navy. The organizations that were largely responsible for procurement in the 1940s were designated Bureaus, each commanded by a Rear Admiral. These Bureaus included: Aeronautics, Engineering, Navigation, Ordnance, and Ships. All items related to flight were procured by the Bu. Aero..
There are extra parts in the box such as a steel belt, extra screws, and metal mounts. The rulers normally in the case are missing, and the cover for one off the bearings has fallen off. Otherwise, it is in excellent condition, with little sign of use. Dimensions/Size: Protractor is 21.5" long when folded and 42" long when open. The instrument is metal but made from non-magnetic materials so that aircraft instruments weren't affected.
The wood case is in excellent condition. The box measures 23" Wide x 9" Deep x 4" Tall. Outside on the lid it is stenciled:

The protractor itself has a data plate with identical information on it. As far as we can tell, it is fully functional, and it extends and rotates correctly.
Also included are original operator instructions with diagrams, illustrations and photos.
