It sounds like this was a gambling model Symphonion.  These models had
a mechanism behind the window that every so often would dispense a
token.  It rarely paid out, based on a cycle of 50 or so.

I have had a couple of these in the past but they were Polyphons
(see Bowers' Encyclopedia, page 155, style 104P, lower left).  I didn't
know Symphonion also made them.  On the Polyphon a bell would ring when
the token or coin paid out, obviously not appropriate in a bell playing
Symphonion.  Is it possible that the Symphonion mechanism is in a
Polyphon case?

 [ Darwin says the instrument is indeed a Symphonium movement in
 [ a Polyphon case.  Therefore the German slogan applies to the
 [ Polyphon gambling model:  "When the (coin) bell rings the coin
 [ pops out."   Maybe the original Polyphon movement wore out
 [ from too much gambling!  Also in the Encyclopedia, on page 230,
 [ upper left, is a similar Symphonion style 132 coin-op instrument.
