I'm not 100% sure of the correct terminology, but I've see both of these in Terwilliger. My miniature DeBruce is missing the upper block screw (or I lost it). Clock doesn't want to run with a loosely inserted tapered pin. Looked on Timesavers but see no obvious direct replacement, though there are some possibilities if I can determine the thread pitch and size. I assume they're pretty standard. Can anyone point me in the right direction?

Thanks.

Duane -

Near as I can tell, DeBruce was the retailer and the clock was made by Kundo. I suspect that other clocks by Kundo would have something that would work. Any chance you can upload some pictures?

wether the top block is held by a skrew or by a pin is not critical as long as the top block doesn´t whiggle with each "beat".The top block has to sit in the respective slot tight, allowing only to hang perpendiculary. The saddle in these KundO´s is friction tight, are You sure You´ve set the beat correctly?

I have a clock that is similar, although not the same back plate. But likely the basic parts are the same. Here's a picture of the screw that goes through the saddle and through the block. The dimensions are in mm.

I've got a "John Wanamaker," a miniature movement made by Reiner in a full-sized mounting, that is also missing that screw. I've tried a bunch of spares I have lying around from various Schatz and Kundo clocks, and all of them are... too small!! I don't know if a previous owner had drilled out the saddle hole larger, or if the large top block pivot screw was always big on this clock. Still haven't found one that fits.
