It's always shocking to me how much they were able to deduce from those fragments. Guess it really helps that gears are so evenly toothed so you can get a very good estimate of the total number of teeth just from a small segment. Also I wonder how many of these existed and were just lost to time by people melting them down after they broke or if this was a one off commissioned piece for someone (which seems somewhat improbable given the complexity, you'd expect there to be similar devices with less features).
