      Hermele 451 030 chain driven Grandfather movement. The tooth count of which gear(s) is/are related to the pendulum length? Is there a chart that anyone knows of to list the tooth count for each pendulum length? The reason I ask is a bit of a dumb one but I have disassembled a couple of “parts” Hermle movements and mistakenly mixed the gears into the same bin. Now I want to insure that I place the correct gear(s) into the correct movements by pendulum length.

        Do you have the book “practical clock repairing” by Donald De Carle? in mine page 59 and 60 have clock trains with length of pendulums. William
