I have yet another example of a Christmas tree box made by Kalliope.
It has fourteen discs of about 7-inch diameter, with all the popular
Christmas tunes.  It has a heavy cast iron tree holder with three screw
clamps that hold the tree as it rotates.  I am fairly sure this box is
illustrated in the "Encyclopedia of Mechanical Musical Instruments".

Fascinating stuff this, Cheers from Tassie
