Dear Tony,

Being British and a fan of the B & H clarinets, could you tell us about
a mechanism that crops up in Brymer's book. The mechanism in question,
and appearing as photographs twice in the book, is called the Acton
patent vent mechanism. This mechanism improves the inherent shortcoming
and acoustical compromise of the low B natural as played with the middle
finger, which in reality is a "fork" fingering (pad of lower ring key
closed, open finger hole, closed finger hole). The photos appear as
figure 13 (after page 52) and again as figure 33 (after page 100).

I have never seen this mechanism in person nor ever had an opportunity
to play on an instrument with it. To you and anyone else reading this,
please tell us about it?
