Perantucci Tuba Mouthpiece PT-88 L Silver Plated
 
The "L"  is essentially the same as the PT-88  with some length added to the outside shell. Therefore, "Intermediate", also in weight.   See the image for details.
 
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.
Model PT-88 was primarily intended as a special applications mouthpiece for low register playing. However, it has found considerable acceptance for use on medium-large bore CC tubas. It serves very well on any BBb tuba, providing a very full, strong tone. It is recommended for advanced players.

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.
