This is a beautiful early Brilhart tenor mouthpiece. It’s the “Designed By Arnold Brilhart” stamped model, and it has a 4-digit serial 1803. Great Neck NY on the shank, and a 4 stamp on the table. Looks like original facing to me, and measures .079, which is about a modern 5. There are some light tooth scratches on the beak that would polish off, and a few other scratches on the body. This is an easy to play tip opening for people looking for a first tenor mouthpiece, or a piece to play in an ensemble or band setting, or even for classical sax. It has a large round chamber and just a little bit of baffle. I love these pieces for their warm, full, pleasant tenor tone. Great for ballads, and not a screamer. This piece would also be a candidate for getting opened up a bit, but since it’s early and in good original shape, I’d just keep it and play it with a harder reed. Most of the old timers played a 4-6 tip on tenon, with a loose embouchure and a harder reed, and they got plenty of tone!
