Friction drive comet for sale. Leather on the pulley will need replacing. I hooked this unit up to a 12V battery and it spins/works nicely! Please note that this is a friction type generator. It will not start an engine, however it is meant to take place of batteries after engine is running. A coil and proper setup will be needed before using it on an engine! (Not intended to produce a spark that will jump a air gap). Please see all pictures for the absolute best description. I think this item overall is in good condition considering its age but my opinion may differ from yours on this item! Will be very securely packed!
