This is a brand new replacement motor for the Jefferson Golden Hour electric clock manufactured from 1949 to 1963. The motor is 110v and the brass gear motor has the correct 27 teeth. If you look at your current motor and it has a worn groove in the gear, the glass is binding and must be repaired before replacing the motor. Often, just oiling the outer ring with clock oil will correct the binding. When the motor is out the ring moves freely and the gear ring can be oiled from the bottom where the motor inserts. This will be packaged for safe and fast arrival to your home. Good luck bidding. Picture of clock is for reference only and not included.
