I found your page through Yahoo.  I am interested in a reference to
repair a couple of music boxes I have had for some time.  They are
basic, one a type of "cuckoo clock" movement, on the other a roof
lifts to reveal a ballerina.  In each case, the door/roof doesn't move
any longer.  I would like to learn to repair myself if it is not too
difficult.  Any advice would be appreciated.
