Regarding the Regina hall clock (sounds like the one I owned!) and
any Regina musical boxes: find the model number -- in plain view on
nearly all -- and contact the Musical Box Society, Inc.  They have
original books from Regina which list every item of every model series,
and can tell you the date it left the factory, to whom sold, I think
case finish, etc.

Merry Christmas to all, and best wishes for a happy, healthful and
successful New Year, From
