Antique Seth THOMAS wood Wall Clock With Stained Glass JJ3A For Parts

I attended an estate sale and acquired this clock. It does have the key. It’s old and marked S. I also see JJ3A. I tried to show photos of what it says so zoom in. It’s scuffed scratched dents dings all over. It might be missing something. I don’t know anything about clocks so make sure you want it. You only get what is shown. Measurements are in photos.
