Hello,
The part you have listed is in fact part of the Sperry Upper Turret power system. Your part consists of an electric power motor (28 volt) with two Vickers hydraulic units attached on either end. One of the hydraulic units was for elevation and the other for azimuth. This power system is the same as the one on the Sperry Lower Ball Turret and the parts were all interchangeable between the two turrets.
If you have any other pics to share of the turret parts I'd love to see them! Hope this information helps.

Thank you John for this information !, I will post the next days other parts of the Upper Turret that I have found.
Question : John do you have for me any pictures of drawings from this Sperry Upper Turret power system inside a B-17 ?, and at which location ( inside the Turret ?? ) was this electric power motor located ?.
