Perantucci Tuba Mouthpiece PT-62 Silver Plated
 
These mouthpieces are all new stock and some also include "Mr Tuba" stamped on the mouthpiece from the factory.
 
Perantucci say the following about this mouthpiece.
Bold and commanding sound for symphonic band and orchestras. Wide 32.50 mm cup diameter enables maximum use and efficiency of the embouchure. Strong emphasis on middle and low register volume and projection.

Models PT-62, PT-72 and PT-82 use unique cups based on modern realizations of classic German design. They are well-rounded and provide a dark centered sound with strong projection. 

Model PT-62 FAST AND STRONG IN THE LOW REGISTER

Cup Diameter: 32.50 mm, well-rounded medium depth
Rim: 7.50 mm, small with sharp inner edge
Throat bore: 7.80 mm

Please note - For mouthpieces purchased online I am not able to offer trials - if you are looking to try this mouthpiece, please contact Mr Tuba at sales@mrtuba.com
 
These mouthpieces are all new stock.  They may have the odd mark on the shank where they have been inserted into an instrument in-store and the box maybe a little tatty, but they are all new stock.
 
I find mouthpieces impossible to take photographs of due to the reflections, so the image shown in the stock image from Perantucci.  I am happy to supply additional images if you send me a message.
