This is a WWII-era Wheel and Flap Position Indicator, Type A-3, as used in aircraft of the US Army Air Force and US Navy with tail wheel landing gear.  According to the Maintenance and Interchangeability Chart dated Feb 1945, the A-3 indicator was used in early versions of fighter P-47 Thunderbolt (see image of the P-47 instrument panel from its flight manual dated 1943) and transport C-46 Commando. It was also used in the fighter P-40F Warhawk according to its service manual.
