Vintage Black Forest Hunter Cuckoo Clock

Vintage Black Forest Cuckoo Clock Hunter Musical. This beautiful cuckoo clock needs someone who can fix it. One of the chains came off and is missing the hook on the end that holds the weight. One of the antlers has a small piece broken off. Other than that it seems to be in great shape. I've tested it and the cuckoo bird chirps and the music plays and the dancers rotate and the weights slowly drop. I don't want to attempt what seems like a simple fix when I really don't know what I'm doing. Please see the photos for makers marks and condition. It is marked West Germany on the brass mechanicals which means it was made sometime between 1949 and 1990. It's approximately 10" +/- wide x 7" +/- deep x 13 +/- high plus the length of the pendulum and height of the deer antlers. I wasn't sure if I include those in the overall height. Think it's a one day clock but I'm not certain. The back says Die Muhle Schwarzwald Holzhacker Bubin Marsch. Packaged this is 8 lbs, 18x 14 x 9. Feel free to ask questions.
