Perantucci Tuba Mouthpiece PT-40 Silver Plated
 
These mouthpieces are all new stock and some also include the "Mr Tuba" stamped on the mouthpiece from the factory.
 
Perantucci say the following about this mouthpiece.

The Perantucci PT-40 is a revolution for large-bore rotary-valve F-tubas.  The cup diameter of 32.00 mm is the same as that of our proven models such as the PT-64 and PT-65. In contrast, the cup is deep and elongated, with a mild transition into the throat.  The rim is narrow, with a clearly pronounced inner edge. The throat bore, 8.70 mm, is exceptional for an F-tuba mouthpiece.  The result is a amazingly full and resonant sound, a particularly good low register, balanced intonation and easy high register. 

Make the “German Orchestral F-Tuba Sound” part of your life!

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.
