Beverly Clock
See also Cox's Clock: https://en.wikipedia.org/wiki/Cox's_timepieceI'm sure Wikipedia used to have a much better write up, and more info on other clocks of a similar type. It's a shame they started on deleting and merging so much of the historic and esoterica - they lost a lot of accuracy and good data in the process.Now the best write up and photo is at http://www.douglas-self.com/MUSEUM/POWER/oddclocks/oddclocks...
