Old vs. New Miraphone Mouthpiece Numbering

[cjk]

There's a conversion chart here:

It looks like the models you mentioned can still be purchased.


I hope this helps,

A couple of years ago on one of my stops at WW/BW... I bought a Mirafone TU-33 that Roger Lewis just happened to have on his desk. Good mouthpiece.

I have an ancient C4 (1960s or 1970s ?), a not so ancient C4 (1980s), and a fairly new TU23 (early 2000s I think). They're all the same, regardless of what the chart says about depth. I also have a Rose Solo and all of the C4s (and Tu23) are smaller.

The C4/tu23's the only model which I have first hand experience where I've got both really old ones and newer ones and have managed to hold on to them.

I don't have the same experience with the other models you mention.

"Deep" is relative to whatever the person writing the specs thinks. I think the depth descriptions on that chart are mostly BS.

I recall that Charlie Krause posted that chart initially.

Wanna buy my TU23 ??

At least the new descriptions are quantified on their website:

I'm glad to see that the difference between deep and shallow has been quantified to minus .039 inches.

These must be the descriptions that are "Supervised By French Technicians"...
