With just a few days to go, it's especially interesting for lovers of
the large upright disc players, as there's an offering of several great
looking examples, including a wonderful Mikado, a fantastic Kalliope
with bells and arguably one of the greatest feats of technological
design to come from Polyphon, an awe inspiring 22 changer with 16-bar
