Seth Thomas has been in business for over 200 years, so they've made a ton of clocks, and I have several. This is one of the later ones. After 1930 they were part of the General Time Company. In 1968 they were acquired by Talley (aka Radio Shack), and things went downhill from there.

According to ClockHistory.com, a flood in the factory forced them to outsource their movements to Germany. This one has a German A-300 movement, and the card inside the rear door says it's a Seth Thomas, part of General Time.

I'm fortunate enough to still have the card in the back door that's in good shape. It's a "Lynton 2W" which I take as being the model (not sure what 2W is—walnut?). The card doesn't have a date that I can decypher. I saw a Lynton 2W with an A-200 movement on eBay, and the card had a 1956 date. If an A-300 is a later model movement, then I'd put this in the early 1960s. Comments on Collectorsweekly.com say it's from around 1961.

Works but there's some kind of problem with the mainspring, as it goes thunk-thunk-thunk as you wind it—something isn't anchored and slips, yet it retains enough power to run for awhile. Some time I'll have to see if I can figure out what's wrong.

One nice thing, if I can actually find info on it—the movement is stamped that it's a German A-300 movement.

Acquired: my father picked it up somewhere.

Circa: late 1950s to late 1960s

Movement: 8 day, German

Current condition: unknown mainspring problem
