I picked up this wooden works movement recently with the intention of using it for parts. I immediately noticed two things. One, it is in very good condition although very dirty. Two, interesting fixture on front plate, bottom right seems to be remnant of some sort of alarm attachment. I'm guessing this is a Seth Thomas due to the square hour hand mounting with pins(corners broken off). 42 tooth short drop. I have looked at Snowden Taylor's chart and don't see anything like it. Im very interested in getting to the bottom of this mystery and no, Im not using it for parts.
