Just got back from an estate sale and here is one you don't see very often. Seth Thomas No. 2, I'm guessing about circa 1875. Yep, it has an old, original unsigned movement that is secured by a slide in seatboard and seatboard hooks to hold the movement down. The old lead weight decends down behind the weight shute. The shute slides up and down. I havn't seen one of these in a long time, am I on track about the year? Unfortunately, both glasses are replaced, nut it was done well with old sticks. I wish it still had the original reverse painting on the glass. Oh well.
