Hello again and thanks for the responses-
I think what we were faced with was a Golden Helm clock with the wrong motor.
We bought the Golden Helm clock at a NAWCC show- we asked the fellow whether it worked, and he said "sure it does!". What we DIDN'T ask was whether it worked and kept correct time!!
Seems he replaced the broken Golden Helm motor with the motor from a Golden Hour clock, and pressed on the gear for the Golden Helm. Gained about an hour a day.
It's a shame that a fellow member would deliberately "mislead" us, but it was a relatively inexpensive lesson in asking all the RIGHT questions....
So right now we might be stuck with an attractive paperweight.
Thanks for the help- any leads on a correct motor are still appreciated!
Best regards to all, Jim.
