The clock runs on a synchronis motor and is extremely accurate.  Copyrighted in 1964 by Edmund Scientific Co., Barrington, New Jersey. The dimensions are approximately 15 inches tall by 10 inches wide. The case is made of solid Cherry with brass trim and was completely hand-made by a certified clock maker. The clock came in two versions, 120 volts, 60 cycles or 220 Volt, 50 cycles.  I Have seen serial numbers on these clocks as high as 2000, so there were quite a lot of them made!  This is truly a beautiful time piece!  It sold for $150.00 when new in 1964.
