Olympus OM System Winder 2 Motor Drive for SLR Cameras Runs - Not Camera Tested

This auction is for a Vintage Olympus OM System Winder 2 Motor Drive for Olympus OM Series 35mm SLR Cameras being sold for spare parts or possible repair.  

The Winder has been in long term storage and has signs of wear including paint loss and wear to the finish.  I have not tested it with a camera so it is being sold for spare parts or possible repair only please.  I did try putting some AA batteries in it (batteries not included)  and bridging the power contacts and the motor in the unit runs constantly when this is done - as shown in the video clip.  Although I do not know if it will work properly when attached to a camera..  The battery caddy pops out properly when the release is pushed.
