Washington: Bureau of Aeronautics 1956. First Edition. 174 pages, original tan printed wrappers. Previous owners' stamp on cover and page edges, old Sanders technical library pocket in rear. Clean otherwise. Very Good. Wraps. 
Contains procedures and many diagrams indicating how electric and electronic wiring should be installed, "one of a series of handbooks prepared to assist military personnel in the general maintenance and repair of aircraft". We would imagine this very useful for anyone trying to restore a period aircraft, since no doubt much of these original manuals perished.
