I have a Hupfeld Claviola player in a three-crown 1908 Rönisch
and am experiencing problems with reroll, which has ceased to work.
Does anyone have any knowledge of the possible cause and where to
look to isolate the problem?  Otherwise the player mechanism is
working well.  Any information appreciated.
