Seth Thomas original Antique clock movement 89C

Seth Thomas antique original mantel clock movement stamped 89C. Movement has been disassembled, ultrasonically cleaned. Springs cleaned fresh oil and grease. Movement has had 4 new bushings installed. Arbor to arbor 3 1/8. Arbor to center shaft 2 inches. Center shaft to f/s adjustment 3/4. Strikes the hour on a gong. Half hour on a brass bell. Will come with suspension rod, pendulum and key. These are very delicate time pieces, i level them in my test stand and adjust the beat. They will run in my stand for at least a week before i box them up for resale. When you receive the movement and mount them in your case it may not be perfectly level, the movement could be out of beat until re adjusted and may not run properly and even stop ticking. These antique movements require lots of patients for set up. If you have no knowledge of how these movements work it may be very difficult for you to set up, you may need professional help. Also i do take cores back.
