This is a German-made tuba mouthpiece, Brass Evolution No. 3. The suggested retail price is around 24,000 yen. Based on the famous German tuba mouthpiece brand "Perantucci" PT-83 (inner rim diameter 32.0mm, slightly flat rim with a width of 7.5mm, bore 8.6mm, deep V-cup Helberg model), it has been modified to be easier to play, such as by reducing weight, to suit various Japanese players. I used it on my Yamaha C tuba, and it produced a clear sound and had a rim width that wasn't too wide, allowing for flexible lip movement. There are some scratches from use and insertion marks on the shank, but there are no dents, discoloration, or plating剥がれ (peeling). This is the mouthpiece only, and the original pouch is not included.
