"The Repair Shop" TV show did a restoration on an old time clock.  The innards did not look as rough as this one and may be from a different maker but it might offer some ideas. 




This is a great series BTW for anyone who likes to tinker with old things.  I binge watched all of the available seasons earlier this year.
