Notes

Industrial hydraulic pumps are perfect subjects for imaginative clockmakers, who can utilize the symmetric arrangement of the pistons to dreate a pendulum. ?GLT? was one of such clockmakers, as he made some unusual clocks with different escapements. A clock made by him with a mysterious pendulum, is featured in the 3rd volume of the Antiquarian Horology, p. 170.
