I have a Denis Wick 7 (yes 7) cornet mouthpiece which I've had for years (don't remember where it came from) and was wondering if it might have been a special order? The cup is about 15mm diameter. It's way too small for me to use, however it is interesting. Does anyone know anything about these? I'm assuming it was either made for or aimed at someone who used one of the really small mouthpieces around in the early-mid 1900s, however I am willing to stand corrected! I don't post here very often, but do read posts quite often, however it's interesting that I'm listed as a "New Member" despite joining in 2004!
