Robbie,  [John]

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

nifty new stuff.
