Selsyn Motor Simplex E7 Projector GE early 3d synchro with jones plug

Description

Now this is a piece of Motion Picture History
Original 3d movies were projected using 2 35mm projectors, they were synchronized using a pair of Selsyn motors, sadly all I have is one of the old motors that came out of a theatre in Trenton NJ when it was being torn down.  The pictures tell the whole story as to the condition so please bid accordingly.
