What fogie is saying here Mick is that a clainet has a cylindrical bore while a saxophone has a conical bore. Also a clarinet uses the fingers to close some of the tone holes and a sax uses keys for all....no finger-covered "open" tone holes. Soprano Sax and a Metal Clarinet

Also, I knew if I looked I'd find one.....This page will ID the type of fingering system your clarinet has for you.

You can have a lot of fun with the thing Mick but you'll end up having to argue with some music stores and repair shops for parts or repairs because they'll tell you it isn't worth it. You can get everything you need and if no one else will overhaul it, send it to me and Bill and I will do it for you (he also makes the lamps, but is an outstanding clarinetist). Or remember, Lowe's sells lots of lamp parts..........

Mick, sometime I'll tell you how it was that I quit playing reeds and jazz. It was one of the few conscious decisions of my life!
