Austin Custom Brass Gen II Series 3C Trumpet Mouthpiece

Description

All Gen 2 series mouthpieces from ACB were recently discontinued.  This is a 3C trumpet mouthpiece that has light insertion marks, but is otherwise like new. Sorry about the trouble with lighting/color on the photos!  Did the best I could with my room trying to insist on a green tint (changed some pics to black & white).
About the Gen II Series trumpet mouthpiece from Austin Custom Brass, from their website:
For 6 years I have been waiting for this moment and it's finally here!
Why add a new series of mouthpieces?
It's simple: we can control every aspect of manufacturing. No more delays via plating (we are doing plating in house). Our tolerances are superb, our quality control is meticulous since we now can control every single piece. Engraving is simple and easy to read.
In general, the Gen II pieces are slightly shallower than their Standard Series counterparts (and have a slightly flatter rim).
3C: A take on a uniquely fantastic Bach 3C from the late 60's. I have never played a 3C like it. I think the added mass and proper matching backbore for this piece make this a formidable all-around mouthpiece!
