QUESTION: I bought seth thomas clock with franz hermle 451-050 movement. Chains and weighs were off. I put them back, but clock isn't working. I'm not sure if movement has all parts / on back side were pendulum goes/ Where can I find picture of back side of movement?

ANSWER: From the top of the pendulum assembly: Suspension spring: this spring is held into the top of the movement and is attached to a rod sticking out the back of the movement.
There is a leader that hooks onto the bottom of the suspension spring. This leader either goes through the crutch or there may be a pin on the crutch that goes into a slot on the leader.
The pendulum top hooks onto the bottom of the leader.
Here are some links to the individual parts on my web site so you can see what they look like.
