I couldn’t really find any helpful information about this mouthpiece. I know it was made in Italy and others who have these pieces claim they are quite loud and powerful.
There is a slight roll-over baffle at the tip and the chamber is medium sized. Rails are quite thick, but workmanship looks pretty good overall. This one is a #8 facing.
No cap or ligature included, although it looks like a standard size hard rubber mouthpiece blank.
