I bought this clock at an estate sale. There were pieces laying inside, so I didn't know if it would work. The time and chimes work perfectly, but the pendulum does not work. I think at least one piece belongs inside the pendulum case. I can't find a diagram online Can anyone help?

You can always try Seiko, they have some parts for their newer clocks but don't get your hopes up ...

Rhythm make a good generic replacement. Merritt's #P-647WP.
The book says it's 5 7/8" wide but it's actually 6 1/2" wide. So you will need a case space that's about 7" wide and about $105 for the part with shipping.

Note, there are many other details that need to be checked before you order a new movement.

That complicated brass piece at the bottom must fit in the case somehow and take impulses from the toothed wheel and transfer it to the pendulum? The plastic knob must connect to it and rotate to turn it on or off? Does the plastic knob slip on the part that sticks out?

Western NSW or just this side of the black stump.

The plastic knob is not going to make the pendulum work so put that out of your mind for the moment.
Yes the shiny pallets do make the pendulum work.

You'll need the plastic cover on the right though.
A small secret; can you spot what a person without his specs on might do?

Thank you so much for all your help! The picture was great. I many many attempts to put it together , but this morning I did it!
The pendulum has worked perfectly for a couple of hours, so it's not just momentum! Thank you again!.
