mechanism</DIV>
<DIV><BR></DIV>in some old pianos (very seldom) we find very strange
mechanisms for tuning, i.e. without tuning pins. Instead of the pins there are
screws. The function is like the fine tuning screws of violins. Did you ever
see such mechanisms? I saw 2 of them in the last 10 years: one Crasselt &
Raehse and one Gebr. Meusel, Hamburg. Have you ever heard of Meusel? I could
find nothing with Google and my Lexikon Of German Pianomakers says nothing,
too. And in a book I read about Emil Lämmerhirt, Berlin, who constructed
pianos with a "Patentschraubenstimmung" (patent screw tuning).<BR><BR>I regret
that I had no camera to make pictures of these historic interesting
instruments. Has anybody else fotos of these mechanisms? At least that
Crasselt & Raehse had a very stable tuning. I came back after 3 years and
the tuning was still fine.<BR><BR>Gregor<BR><BR>
