That was an old Bechstein I was working on.  One advantage I can think of is
that with the wippen connected to the key, you get no separation between the
capstan and wippen heal upon return.  That should have some advantage in
fast repetition.  There will be less friction because there is no sliding
between the contact points.  It is a bit of a pain to take the stack off
though.

> There was a recent thread where someone proposed replacing a set of old
rocker capstans with modern, and there were a number of replies that
suggested there were some advantages to the rocker capstan setup. Perhaps
lower friction was one advantage? What, if any, were the other advantages to
the rocker design?
