Sounds like a stainless steel Kellyberg to me:

Hope this helps!

Well, this is a mouthpiece thread, and I have been fighting between two mouthpieces lately. I really like the feel of my Helleberg 7b (great rim and cup), but it doesn't let me put as much air through as I want (or should). I have a Curry 128D with a similar rim, but too deep a cup (for me), but with a much larger throat that lets me put more air through it.
Does anyone know if there is a mouthpiece that combines these two elements (Helleberg 7b rim and cup with a large throat)?

Also, if there's a Parantucci mouthpiece in a similar size, my teacher has a lot of those, so he's offered to let me try one if it's about the right proportions.

Okay, here is how you look up things that are comparable to what you have. In your case, I went to http://www.dwerden.com/mouthpieces/tuba.cfm and selected one of the mouthpieces you liked and clicked on the Miraphone 31 at "Rim / Inches" and came up with this list of mouthpieces, many of them showing the bore diameter for comparison - http://www.dwerden.com/mouthpieces/tuba ... pare=33.00 . You can see that there are a lot of mouthpieces with that inner cup rim size and bores from 7.4mm to 9mm. Notice the Josef Klier mouthpieces and how they are listed. They have gradually shallower cups as you go down the alphabet with the bore sizes adjusted for cup depth but the inner rim size ALWAYS stays the same. Your PT 50 shows up on this list, too. You don't have to mess with re-boring mouthpieces to experiment with the throat size for a given rim. Whatever bore you would like is probably already available. There are some pretty pedestrian mouthpieces on the list, Like Bach 7 and 12 and The Klier T3 series (AA is the deepest, E the most shallow).

Experimenting with mouthpieces is fun and a well equipped shop will have a lot of them for you to try. But, try to lock on to one you like and one that works for you and stick with it for a few months until you have proven it out, one way or another.

Once Paul Sidey gets back up and running, try one of his "original" or "classic" profile mouthpieces. His marketing is almost word for word your stated parameters.

BTW -- How is Paul doing?

The Sidey mouthpieces (unfortunately - I'd prefer the 1.30" id myself, but really like the Sidey rims) bracket the 33mm size - the original is at 33.46mm and the smaller rim is 32.6 -as I remember - A Giddings and Webster Alan Baer MMVI is 33mm and probably pretty close to what I think you're describing. I have a few of each and will say that they are all extremely well designed and made. One thing you may consider - since you're talking stainless, is to find the cup and backbore that works for you, and have the rim re-profiled. Good luck - I'd also like to hear if there's any news on Paul Sidey - The few times I've dealt with him he's always been great to work with.
