Yes, you should register your Qualite Excelsior box with the
Musical Box registry in England.  He registers music box information
that is sent to him.  He is very pleasant, with a great sense of humour.
Address:

  The Registrar, c/o 5, East Bight, Lincoln, LN2 1QH, Great Britain

His name is anonymous, but he is very helpful.
