alto clarinet

This is another outtake of our recent session with Muneer B Fennell on 6 string cello and me on alto clarinet:

Does anyone here know anything about the quality of alto clarinets made by Conn in the late 1960s? How are the mechanics and intonation? Thanks.

I've got a Bundy alto clarinet in with a neck that is a bit loose. What do you guys use to tighten these? The size is smaller than tools I use for flutes or sax.

I did a quick search of the site before I posted this question but anything with alto in it is doomed to bring up the wrong posts. Alto clarinet? Why do I not hear people playing alto? Bb soprano and bass clarinet are clearly the two most popular, especially in jazz but why no alto clarinet...
