I dont recall seeing manual reg keys on a bass, but am sure there were/are some. I did have an old [1920's] Conn alto cl with the pair, gave it to the Shrine To Music a year ago, Debbi Reeves may have dated/restored it for display. My 1940? Conn Bass[low E] has an earlier Double Reg Key configuration, a bit difficult to make it work properly. My Selmer 32/33 [low Eb] has a well-worked-out D R Keying, which I need to adjust occasionly [usually by a bit of corking] which works very well, giving good tonality and ease of response to the lower clarion notes. It shares a ?5 mm? dia. vent hole [as the lower reg vent] with the "pinch Bb" tone hole satisfactorily [sp?]. There are a number of configurations [patented, have #'s] by the major makers, the latest I know of is to Yamarho [sp?] of Yamaha, which I have yet to see on Y's basses, has anyone seen it?, played it?. Interesting thread! Don
