Hey Paul, just picked up several clocks and parts and books and stuff from a guy who wanted to sell it all,(couldnt afford ALL, but came away with a bunch) anyway one of the books I got is a New Haven clock and watches, Tran Duy Ly and thumbing thru it I saw one very similar to your, originally had small finials on the bottom of them blocks and then a little larger finials on the flat roof pc. just above. all I can see is that it was called a No.251 zebra veneered, 17 3/4 inches tall with a 5 1/2 inch dial. came in 6 different varieties as far as time and strike.
Have fun, William
