As to the question of having 2 [or more] individual register keys operated by the left thumb,YES, it is shown in copies of several old patents I have, and I gave an early 1900's Conn alto cl with the 2 to the Shrine to Music, Ver. SD, [Debbie] who had never seen such either. Yes, oboes and bass/alto? cls have effectively 3 register keys, I have experimented with a 4th on my bass cl using a trill key masked down to a small hole [didn't work very well!] because the "shift-over" from clarion D or D# to E needed improvement!! As in other situations, compramises are seldom very good! Don
