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-1 was made by Bendix, part number 739U-03, and has a serial number prefix of AF44, indicative of a 1944 manufacturing date. See spec sheet in photos.

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 window rotates and indicates hundreds of miles per hour. 

It is in good condition given its age, although it is reading is inaccurate, which can probably be opened and repaired if desired. The dial and glass are intact. The dial has some slight water marks, see photo.
