It's a backbore number. Older standard-weight Prana mouthpieces often had the 77 backbore. These days they more commonly have an 82 backbore.
Different mouthpieces can have different backbores at different times for different reasons. |

Thanks for the reply! Do you know what the differences between them are? And if I have an older B4 WITHOUT any numbers designating the backbore- which one is it then? _________________ Principal trumpet Gothenburg Opera Orchestra

Happy to help.
A larger number is a wider taper and a smaller number is a more narrow taper.
The Classic (non-Prana) mouthpieces do not have backbore numbers stamped or engraved on them. If there is no number on it I have no way of knowing exactly what it is. As I mentioned in my previous comment, different mouthpieces can have different internal specs for different reasons and at different times when they were made.
I assume that the one with '77' is a Prana. Prana mouthpieces will either have 'PRANA' stamped/engraved on it or will have the letter P after the size. If it is a Prana then it has a larger throat and backbore than a Classic (non-Prana). |

Thanks again!
Looking forward to try them both, and see/play/hear if there's a difference. _________________ Principal trumpet Gothenburg Opera Orchestra
