Schlagabschaltung Cuckoo Clock Missing Parts Doesnt Work

Schlagabschaltung Cuckoo Clock Missing Parts Doesnt Work. Item is missing the wood pieces that attach to the metal chains. And is also missing the other wood part attached to bottom. The bird does make the sound and cones out when you play with the metal strings. There are photos posted of the inner part of the clock. Im not sure if there are parts missing from onside. May be also missing other parts as well. Overall the clocks' wood looks good. Item will need repair and does not work
