Bach cheap #1 custom lead trpt mouthpiece

Product Name: Bach cheap #1 custom lead trpt mouthpiece
This is a one of a kind mouthpiece probably the only one like it in the world, I had this made for me around 1978 , I was playing long and hard and need a tool to help me and this is it look at the pictures see the backbore is at different sizes and the throats are #28 ,this is a once in a lifetime opportunity to own something that took 3 men to create after trial s and error , u must blow it to believe cheap it, if you don't or can't play wide diameters then this is not for you Thanks and God Bless.
