I picked up a couple of "new" clocks last weekend and would appreciate any info on this one that anyone can give me. It's my first clock made of some kind of stone (slate, granite, concrete with paint?). It is held together with wire and sealer and there is some kind of paint or lacquer finish on it also. It is 12-3/4" long, 12-3/4" high, and 4" deep. The only markings on it are F.H.T. on the dial and the back cover. Nothing that I can see on the back of the movement (I haven't taken it out yet to see the front). I'm sure one of you experts has seen one of these before and knows what it is. Thanks!
