Does this qualify as an Official Reference for Observatory Testing?

These are amazing. . .
. . . obviously, can anyone shed light on the Potter patented detent escapement? It looks like there's some kind of funky arm coming off the detent with, uh, maybe the passing spring mounted on it??? Jack
There are more than three
There are more Potter's in this collection than these 3. Perhaps if you badger The Crown Prince enough he will post more pics of the group and give us more backround on Potter.
