Description: WWII AN 5735-1 Directional Gyro - Sperry (?) One early AN 5735-1 Directional Gyro instrument as most likely manufactured by Sperry Gyroscope Division for the war effort that is is essentially complete and ready for drop-in display into your panel.No data plates here - both of the metal data plates on the back of the cabinet have been removed. The instrument appears to have been overhauled in May 1975 and doesn't appear to have any radium paint on the components. No paperwork. The yellow tag on this one is just someone's inventory tag. Looks as if it has been repainted at least once, accounting for the crappy paint job on it. Sperry Gyroscope was one of the original prime makers of the AN 5735 directional gyro. Given the government's excessive need for this instruments (which were found in everything from the lowly basic trainers like the BT-13 and in every transport, bomber and fighter aircraft up through the Boeing B-29 Superfortress) it became pretty clear Sperry couldn't meet the excessive demand. Contracts for said were awarded to both General Motors (who tooled up a special instrument division just for aero instrument contracts) as well as JAHCO or Jack & Heinz Corporation. All three firms churned out thousands of these instruments in a short amount of time. The early instruments were interesting in that they were all metal cased. By late war many of them were in plastic cases. This is an early instrument. This one - appears complete except for data plates. Components ride smoothly in housing with no binding or grinding when the directional knob is turned. Nothing rattles or clunks inside. The directional knob can be turned as well with no hesitation or stiff spots. Graphics on this instrument are bright white and appear to be NON-RADIUM. No paperwork for this one.Can't hear any clunking or rattling around on the inside of the instrument. No additional mods or drop damage to case. No evidence of water or dust or bugs or dirt inside - just a little dust. We'd kept this as a parts source for other 5735 units but at the end of the day we've got more than enough directional gyro instruments and no longer need to build and mix and match. I can't think of a trainer, transport or bomber that didn't use the AN 5735-1 gyro during the war years through present day. What you see in the photo series is representative what you get.
