This clock is complete and will run for short periods - sometimes an hour or two and sometimes for a few days. I think it just needs a complete cleaning and adjustment. All the parts are there except for the one and one-half volt battery. I have used a D size flashlight battery for testing. I am told it should work. The case is in good condition. The two screws at the bottom for adjusting the case to make it vertical are there and the screw for securing the pendulum is in place. I have had this clock for several years and I am reducing my collection as I am retired and can no longer afford to have experts work on my clocks. Buyer must pay all costs for packing and shipping either by Canada Post or UPS - buyers choice.
