WOW
I chased these tubas for 20+ years, and things never lined up for me to ever actually buy one.
I would absolutely love to buy this, but good golly dangit that's just not going to happen within the next 5 days of an auction.
Guess I'll at least right click and save the photos, Merry Christmas to me.

I'm thinking the title was edited to include "C".
I sorta assumed it was a B-flat (with the LP/HP slides included)...I dunno why I assumed that.
If it played down to pitch with the shorter slide (??), maybe the longer one could be inserted SUPER-fast every time there's a low F in the music.
I wonder if a former Texan sold theirs to this person...
...I don't see any soldering in the picture, and I'm thinking that the particular instrument I've seen in-person had been "put back" the way it originally was, so...(yet another one ??)

This tuba is a CC. High pitch and low pitch slides are interchangeable. I acquired the tuba about 5 years ago on Ebay. There are no more than 5 Conn rotary tubas in existence. The medal is heavy! Valves are "squishy," the reason why Warren Deck installed Alexander valves on the Geib tuba, currently owned by Mike Lynch. Mike told me that he thought the same (or similar) interchangeable slide might have come with the Geib tuba, but it must have been lost years ago. But, he is not absolutely certain. There is a one piece bell, rather than the two-piece bell on the Geib tuba. This Conn plays well- and is typical for Conn during this era. It definitely has the distinctive "Conn" tone from that era. The tuba is in amazingly good condition.

Is the extra slide a low pitch slide or a BBb slide? it almost looks like it has enough tubing to put the tuba into the key of BBb.

Update: The horn definitely plays best as a BBb (with optional slide in).

It's hard for me to see an additional two of tubing in that longer slide, but it's just a two-dimensional picture, so it probably is.

With the crooks and straight sections, 6” X 4 = 24” could add up. I have a BBb conversion slide for a Conn “Donatelli”-style CC that came out a high school in mid-Michigan. Why did they have a Donatelli CC from the late 1950’s? They had a string program back then, so I guess they felt they needed a CC tuba.

Yes sir. When I look at the difference between a regular slide and one that does a curlycue, I always consider that has to be enough longer including the regular bow of the shorter slide.

My Mantia double-belled baritone came with double backed "W" tuning slides.
With them installed it plays at A=435.
I had to have new ones made without the doubling back to get it to A=440.

As an exercise in wading through ads on the old site, is this the discussion of the previous sale?

How much do we change over the years?
I still am tickled by the tuning slide on a tuning slide.

first time viewing this on my laptop...
I formerly did NOT see that the center portion is a slide.
ok...I'm now a believer.

Well ... Apparently I wanted it back then, too.
That was back between kid #1 and kid #2. Going to be considerably harder to get this in my house now...
