WWII USAAF B-17 Gun Turret motor part K-3 Sperry Gunsight
Here we have part of the internals from a K-3 Gunsight as fitted to turrets in aircraft such as the B-17 Flying Fortress
This part carries a Sperry part number of 801531 and was made the DIEHL company which was part of the Singer Co contracted to produce electrical parts for the K-3 Gunsight
There appears to be no damage to this unit and all the cogs rotate freely. This is not a wreck recovered item.
The motor has not been tested and it is therefore sold as a collectible item although given its excellent condition it may be suitable for a turret restoration project
