Well, I carefully applied small amounts of oil on the axles of the gears & with a little help I got things turning again. after a while it was ticking away on its own. I hooked it uo to 12V & away it went! Very happy about that. This clock came from my parts car that was parked in 1982. It possible the clock was working at that time but after decades of sitting the gears got tight. I must have tried it many years ago which would explain why the spring was already wound. Pretty cool to see it go after what was close to 40 years of no use.
