This is a dark walnut or mahogany finished Antique Seth Thomas wind-up Metronome. It is a real treasure to find and was made I think in the 1900s, however Seth Thomas started producing metronomes in the late 1800's so it could be older. From experience, this is a Model No 5, but is unmarked as such. They are known for their high-quality clocks, and their quality shows in the beauty and performance of this metronome! This metronome still runs strong despite having no known service records. It is complete with only one missing part: The wooden pyramid at the top. This part makes the original front dust cover difficult to hold "closed". Becauser of this, there is tape residue visible around the top. Nice patina on the brass trim. Lacquerappears to be doing its job. The dark walnut or ebony stained wood case is made out of solid wood (no veneers) and has a pretty deep black brown look to it throughout. The original finish is satin smooth over the case with a very tight alligator (rare, usually others have some heavy wrinkling all over) and hides fingerprints well. It still retains some original shine which you should be able to see in the close-up pictures. The original front dust cover door is a perfect match to the rest of the case. Since this is an antique, there are some signs of age-related usage on the instrument, but no abuse.
