Antique Regula German Cuckoo Clock Carved Wood 3 Weight Hunter Deer-Untested

See last 4 pics for: a leaf to the left of the stag having some edge damage, unsure how top stag piece hooks in there is a loop fastener to the back, 2 small protruding nails on edges and 2 small wires just above the bird/man who pop out to somehow attach. On the backside of clock I can feel 2 bottom corner nails just slightly protruding.
