I am copying the Palanca from a private collection in Frankfurt. My copy is a real eighteenth century flute. I use the mouth hole and bore as precisely as I can but believe to have found back the original intonation which is amazing!
I think I can say that my Palanca is somewhat different from the orther Palanca's on the market. Whether you like it better is a question of trying and taste.
Picture of the original thanks to Mr. Spohr!
For the owner the pitches are 417/427/435 Hz However, for most players the pitches are essentially higher, about 421, 431 and 439Hz.
I have recalculated the pitch 421 to 417. So far for everybody this was satisfactory for 415, usually pulling out a little bit of course.
