Many useful websites have further information about these clocks including methods to synchronize them. They are spring powered and electrically rewind every hour. They used two old fashioned #6 dry cells inside the case to power the rewind but D cell packs of batteries are supplied when restored.
Every clock has the winding and clock mechanisms cleaned, reworked and calibrated and the case is restored and painted to original color.
