To any one able to provide information or assistance.
This is german Schneider Cuckoo Clock. Three weights all weight are 500 units. The clock keeps perfect time, the music box plays at the hour and on the half hour and the cuckoo keeps the correct number of chirps per hour. The problem is the music box chain drops faster than the other two chains. It is my understanding (however I could be wrong) that all three weights should drop at the same amount and/or stay even.
Any assistance with this and how to repair would be greatly appreciated.
