Roenisch Claviola 88-Note Player Piano
By Adam G. Ramet
The player mechanism is a Hupfeld-built one. Hupfeld built instruments
with 73-note scale and 65/73-note players turn up from time to time.
I should guess this was converted to 88-note operation later in it's
life. I guess the instrument was originally built some time between
1905 and 1910.
[ Colin Campbell confirms your guess: "I meticulously counted the
[ tubing from the stack to the tracker bar (in situ). There are
[ 73 tubes from the top of the stack to the tracker bar." -- Robbie
