    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.

    An interesting movement and still a bit of a mystery, it would have been a shame if you parted it out. The missing lever is a release for an outboard alarm mechanism. The closest match is one used early by the Terrys for the window shade alarm and later by Seymour, Williams, and Porter for their outboard alarm. However, the lever is attached on the left side of the movement in the ones pictured in the Bulletin (No. 154 p. 1425 and No. 157 p. 339) and in the one example I can find here. I have a couple variants of the SW&P but currently can only find the one. Yours has an arrangement similar to the 8-day E. Terry & Sons example in Bulletin Supplement 18 Figure 85 p. 41.

    Thanks Troy for your research. I have it up and running with just a little intermittent beat problem that I am still working on. I don't have a case for it and I am hoping to get a little more info before putting it into something that is not appropriate.

    Eli Terry Movement. You are missing the release levers for a window shade alarm mechanism. Rare movement .

    Thanks Frederick, Since you made the identification, I have looked at the few pictures on line of the Window shade alarm mech. They all are mounted on the left side of the movement plate. Mine is on the right. Have you seen this arrangement?
