The AN5774-8 unit was used in the US Army Air Force fighters P-38E Lightning, P-40 Warhawk, P-47 Thunderbolt, and P-51 Mustang according to their Maintenance Interchangeability Chart dated Feb 1945, as well as having been used in other military aircraft post-war.  

This instrument is in reasonable condition for its age. This particular instrument has a stamp of the US Navy, so it was likely used in a USN aircraft.  Measures 3.25 inches diameter and ~3 inches deep.
