This pre & early WWII-era Turn & Bank Indicator Type A-8, made by Bendix Part No.1718-2S-A2 for the Air Corps US Army, was used across virtually all its aircraft during WWII, including bombers B-17, B-24, B-25, B-26, fighters, P-38, P-39, P-40, P-47, P-51, and transports C-46 and C-47. Imprinted on the face, but barely discernible in the photos, is "AC US Army" (Air Corps US Army), and its serial number prefix is AC41, indicating the manufacturing year 1941. The A-8 included a filter for the vacuum air which is drawing across the gyro to power it while in flight, see spec sheet in photo gallery.
