Hi, I Just bought a Herr cuckoo clock of unknown age. It's missing the 3 weights, the oak leaf pendulum, the topper, the end of the horn, and the rear door with the gong. The clock has dancers and a music box. The bellows look good, and the clock looks fairly clean inside. The woman I bought it from (online) said that the dancers dance when she pulls the chain, the music box works, and that the bird comes out when she opens the door. She said the clock is about 13" tall, by 7" deep, by 9" across. Not sure if this clock will work, but hoping for the best. I'll need to make a back door for it, and attach a gong. But not sure yet what size gong or pendulum it requires. From doing a little research, it sounds like the clock might call for 320 gram weights. Thanks for any info!
