NOTE - clock is NOT in working condition - it appears to be overwound, and may have other mechanical issues - I'm not by any stretch of the imagination a clock expert - although note that the works look very clean and bright in appearance - SOLD AS IS AS FOUND. 

Smith Patterson & Co. was basically the Tiffany & Co. of Boston in the late 19th-early 20th century - particularly known for high quality jewelry, watches & clocks. Chelsea Clock Company was founded in 1897 and still operates today - at the time, their reputation for quality was peerless, solidified by a contract with the U.S. Navy for ship clocks. 

Note some scratch/wear to the face, but still a great looking piece, with heavy wood housing, and nice decorative bronze hands and numbers. Winding key is present, but note the speed adjustment key is not. Screws are all still present but note, one screw is loose due to the hole being stripped. Some specks of white paint splatter from the clock apparently being painted around in the past. 

Definitely worth repair/restoration. The Chelsea movement is worth the price of admission itself for parts. Please review photos carefully to make your own determination of condition and appeal, and don't hesitate to ask any questions prior to bidding - thanks for looking!
