Perantucci Tuba Mouthpiece PT-38 Silver Plated
 
These mouthpieces are all new old stock and some include "Mr Tuba" stamped on the mouthpiece from the factory.
 
Perantucci say the following about this mouthpiece.
Model PT-38 is developed from PT-36. The cup is slightly wider at the top third of its length; the rounded rim is very comfortable, even for long playing sessions. The mouthpiece has a similar sound to the PT-36 due to a slightly tighter back bore. This model is recommended for players with large lips who prefer a clear symphonic sound with great power and projection.
 
Cup: 34mm diam. Deep funnel-shaped, moderately rounded at bottom 
Rim: Width 7.5mm. Rounded inner and outer edges 
Throat Bore: 8.3mm 
Standard Large Shank for most European Models (recommended for most instruments)
 
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.
