I found this clock on snclocks.com, here is the link: VR-384 6 Month Duration Bodenstanduhren - SNClocks I've meticulously counted the wheels and pinions that I can see, but some can't either BE seen, or are only partly visible. Here are the counts I do have: Barrel: 168 teeth, 16 pinion teeth Center wheel: 194 teeth, 18 pinion teeth First wheel: 144 teeth, 8 pinon teeth Picture #8 of 17 is where I'm not sure to figure. The top wheel is the minute wheel, and I think 72 teeth. The intermediate is 72 teeth. The center wheel has 72 teeth. The escape wheel has 60 teeth, but the pinion that drives it is hidden behind the plate. How many teeth would be on that escape wheel is what I need to know, and finally................ How can I figure the wheel diameters with what is given in the pictures and tooth counts so I can use the right cutters or modules? With a complete wheel count, I know I could then figure pendulum length, correct? The reason I like this clock is because everything is in an upside down configuration, which I like, AND, it is a 6 month duration in one winding. I may have left some details out, but any help would be appreciated! Thanks!................................gary Post Script: I can't post any of the pictures because they are owned by snclocks.com.
