Hi Nico, perhaps I can help.  Although I don't possess a Kalliope with
22" (58 cm) discs, I made two videos with two different Kalliopes in
this size, recorded 2011 in the "Nostalgie Palast" in Nordhorn,
Northern Germany.  Here is a 22" Kalliope with bells:

and here another one without bells:

As often, I had a seeing camera leader, the owner of the "Nostalgie
Palast", who is originally a Dutch man by the way.  So I think, you
will find out, if these Kalliopes have bass dampers or not.

Best collector's regards,
