I don't recall ever seeing such a description in the AMICA Bulletin. Would you consider preparing something for Robin Pratt <pianola@aol.com> for publication in the AMICA Bulletin, and ultimate publication in the AMICA Technicalities which I edit and assemble?
Sincere regards and many thanks for absolutely fascinating discussion. Very much appreciate this daily feast of nifty new stuff.
