JK Exclusive 3C Equates to…?

[the elephant]

I have a nice JK Exclusive 3C (not the newer "Classic Exclusive" line). Can someone here who is familiar with the Josef Klier Exclusive line tell me which Miraphone mouthpiece (using the very old numbering system from the 1980s) it is the closest to?

I understand JK makes all of Miraphone's mouthpieces right now, and they are the genesis of the current numbering system, which I know nothing about at all. I cannot find my favorite old designs using the new system and have to use the old one as I know it pretty well. This is why I need to know whether this C3 equates to one of the older Miraphone designs that JK now makes… or if the C3 equates to a newer Miraphone model… or that the C3 is strictly something sold by JK under their own marque.

I have asked about this in the past but never really got any conclusive answers. So, any Josef Klier "experten" out there?

I'm guessing you already know this information, but it's all that I know, and perhaps others would like to see it:

Specs and old-to-new Miraphone mouthpiece model numbers:

Specs for the mouthpiece you're referring to (right?):

Nothing matches up exactly, but maybe the TU27/C10 Rose Solo is sort of close?

That chart has the old C4 listed as "deep". What were they smoking when they typed that up? The C4 is tiny!

I guess I want to know whether the JK Exclusive C3 that came with the Kalison DS tubas from TE back in the day is actually a low-price *copy* of something else.

I don't think JK sells copies.
Here a list of their Exclusive line

Yes, I have read all that. I want to know whether it is a copy of something existing, whether a direct copy or an improved one. Just curious. It very much reminds me of a very specific mouthpiece and it was produced for that to-remain-unnamed man at that to-remain-unnamed mid-Atlantic tuba store, and he was always into some sketchy stuff. (Many of us remember that unnamed person's penchant for litigation, some of it related to posts on the original BBS in the late 1990s. I do not want to poke the bear, so to speak. I am wondering if this JK mouthpiece is like the other pieces that he included with horns he sold, some of which were direct knock-offs of mouthpieces sold for much more money by other makers.

Again, I am trying to cagily ask in public whether the genesis of the C3 is some other mouthpiece, in the hopes that another old fart like me will wander in here with the definitive answer I am seeking.

I don't think JK sells copies.

They do - "USA-Line" 18, 24, 24 AW, 25. They may not be exact copies, but then Bach's 18 isn't an exact copy of a Bach 18, etc. Not that this has anything to do with the question.

A scenario that others may well dread.
