Hi Group,  Rich Schaffer asked about a Kalliope 52.5 cm disc
musical box with bells.  In the "1905 Kalliope Schatullen"
the largest instrument shown plays a Stahinotenschelbe 45 cm
Durchmesser (45 cm disc).  At 45 cm with Glocken (bells) it shows
model Kalliope-Glocken-Spieldose No. 108 G.  45 cm models without
bells are No. 108, No. 107, and No. 107 D.
