Made in July 1978 and very little time on service, We found No dust inside or on the roof of this clock. Looks like it was hang then put away, you can see on the close-up picture of the Dial. The White numbers are like new condition.(that picture was untouched). The music box plays "Kaiser Waltz" at the top of every hour as the Dancers goes around. We did cleaned and oiled the movement and all metal parts. All original parts including the weights. We test-run it for 4 days before packaging it. Measures appx. 12 inches high by 10 inches across and about 5 ½ inches deep. Comes with easy pictured set-up instructions a numerical certificate and a 3 page article about Cuckoo Clock origins.
