Used Denis Wick 6BL Heavytop Trombone/Euphonium Mouthpiece

This is a fair example of the Denis Wick DW6880-6BL Heavytop Large Shank mouthpiece. 

The mouthpiece has been buffed and sanitized.  There are signs of use and plating wear inside and out, but nothing that will affect the playability of the mouthpiece.
