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> <HR> Invite your mail contacts to join your friends list with Windows Live Spaces.
