Very nice, 1921 Seth Thomas Tambour #74 mantle clock with 113 movement. Movement was rebuilt with several bushings replaced. All three main springs were removed, cleaned, and oiled. Beat was adjusted and has been running in test for several months. The chime and strike work as it should. All hammer pads have been replaced. The bezel and beveled glass show some wear but normal for its age. If you have any questions, please ask. I have rebuilt more than 100, 113, and 113A movements over the years. I’m trying to thin out my accumulation of clocks and sacrificing this one at such a low price.
