Perantucci Tuba Mouthpiece PT-64-S Silver Plated
 
These mouthpieces are all new old stock and also include the "Mr Tuba" stamped on the mouthpiece from the factory.
 
Perantussi say the following about this mouthpiece.
Model PT-64 provides a lively and exciting sound with a clear core and excellent projection. It also allows great flexibility and a remarkable tone colour for the CC tuba. It is recommended especially for the F and Eb tubas, giving great power and a commanding nature for solo performances with large accompanying ensembles, or for use in executing the high-range orchestral literature. This is one of the most popular tuba mouthpieces today.
 
Cup: 32mm diam. Moderately shallow cup, bowl-shaped 
Rim: Width 9mm. Very round cushion 
Throat Bore: 7.8mm
S-Shank  - American Shank for Instruments with small receivers

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 the 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.
