I think that this Kalliope is the Model 201.  It came with bar bells
or saucer bells; the discs were 64.5 cm.  I have the smaller version
with 12 saucer bells that plays 52.2 cm discs, Model No. 176.  There
was a larger one that played 64.5 cm discs, again with 12 bells.

Hope this is of help.  I could do with some more discs for my machine
if anyone has any for sale.
