Best Brass 1C Heavyweight Trumpet Mouthpiece, Excellent Condition

Description

I bought this new some years ago, kind of on a whim.   It's it's still in nearly-new condition; probably played less than an hour. The silver is shiny and almost unmarked.
Best Brass is still around, not sure if they're still making this model.
The 1c size feels to me more like a Bach 3, and the cup isn't as deep as a Bach C, more like a Giardinelli C or a Bach D.  The throat seems about standard, and a "pencil test" of the backbore shows it to be a little more open than standard.
This has a very bright but solid sound, and the weight balances a trumpet nicely, but it just didn't fit my playing style or agree with my other mouthpieces so that I could move between horns easily.
If you regularly play a Bach 1 & 1/2 or 3 or the equivalent, and want to try a heavier mouthpiece for lead playing, this could be it.
