This is very anoraky, but here goes. Since January, I have been using a Black^ Hill 1-0G mouthpiece, which I bought in New York in 1994. It also has a number "2" on the shank. It is a one-piece mouthpiece with no interchangable parts. Does anyone know anything about these mouthpieces? Is it the same as a current model Greg Black 1G mouthpiece? I tried looking on the internet, but the only references I could find to Black Hill mouthpieces were for trumpet mouthpieces.
