Ansonia Triangle Mantle Clock

Unusual shape and rather plain for Ansonia clocks. But nice and rather old from what I have found about Ansonia and the type of materials used in their early clocks.  There is a dark wood base to the clock.  4 round feet screwed into the wood. Has a key to wind and set. Clock face has a hinged window that opens in front.  Also a hinged door in back to the clock works. A brass plate on the inside also denotes Ansonia Clock Co. New York USA. Abovethat there is a small lighter, hand engraved marking that reads s dtyX s or sdutyx5.  Have had several people try to assign an age or worth to this clock and they have never seen one like it before. Beautiful chime tone!
