TubeNet

I have been performing professionally on bass & tenor trombone for a couple decades and I just acquired my first tuba to finally get my doubling game together for some pit orchestra and big band jobs I have coming up. It’s a Mahillon 390 (4v 3/4 BBb .625 bore). I’ve been trying out a handful of different mouthpieces and the one that clicks with both me and the horn is a Yamaha 65. The one I have in the old blank style (left) is kind of chewed up, so I bought a new one (right). Turns out the new style is just over a whole ounce lighter than the old style. I greatly prefer how the older/heavier version both plays and sounds in every way, and it’s not even close.

So, I am trying to track down an example of the 65 in the old style blank in better condition than the one I have. I haven’t had much luck so far…can anyone here help me find one?
