U.S. Range Indicator And Flight Computer - Nice Used Condition

A great set of U.S. Air Force measure equipment. This set compromises two Flight Computers. A black flight computer A.C. Type G-1 and marked 'Property of U.S. Army Air Forces' and dated 1942. The white flight computer is also 1942 dated and makers marked G Felsenthal & Sons. Both are in mint condition. The range indicator is in nice used condition and marked U.S. Navy-Bu AA range indicator. Clearly 1943 dated. A very interesting lot of metric equipment.
