I think this one is early 1900s and it is a beauty. The wood design and case is in awesome condition and the clock works perfectly and keeps perfect time. It chimes as it should on the hour and dings on the half hour. It comes complete with winding key. The inside back panel cover has handwritten dates of 1988 and 2003 for service work. It stands 11 inches tall, 8 inches across the front and about 6 deep. This clock is absolutely gorgeous!!! Read the label on back of clock and it says patented 1870.
