$75.00

The Army Type F-1A Airspeed Indicator was used across a number of US Army Air Corps and Air Force aircraft during WWII, including heavy bombers B-17, B-24, B-29, medium bombers B-25 and B-26, as well as light bomber A-20, according to the Accessories Interchangeability Chart dated Feb 1945. It was also used in versions of US Army Air Force WWII fighters P-38, P-39, P-40, P-47, and P-51.  This F-1A was made by Kollsman, part number 739U-03, and has a serial number prefix of AF44, indicative of a 1944 manufacturing date. On its face is embossed AF US ARMY.

According to the spec sheet in the Index of Army Aeronautical equipment Volume 6 Instruments, dated 1944, the Army type F-1 is a sensitive airspeed indicator. The pointer makes one revolution every hundred miles per hour. A smaller inner dial indicates hundreds of miles per hour. 

It is in exceptional condition given its age.  The dial and glass are intact. There is a small bit of debris inside the glass that should be able to be remove once opened. See photo.
