I see it has an FV number on it, so a vehicle part, also painted silver so an internal fitment on an armoured vehicle...........that is as far as I have got with it. A large motor in comparison to the output drive, so doubtful is is a turret traverse motor. The Lucar is a bit odd as it is not protected, input current is through a screened harness with plug and socket. This may be because the drive end is encased and the wire from the Lucar goes to a warning lamp adjacent, maybe :confused:
