The left chain on my clock came off. I am trying to find a parts manual to help reinstall the chain. I inherited this clock from my grandmother. I don't know how old it is. It is over 65 years old because I used to help wind the clock when I was a little boy in the 1950's. I believe the serial number is 26673. Could be 20673. It is stamped on the back of the clock mechanism. The first "6" is not stamped clearly.
It could be that the ratchet mechanism is broken.
