It'll make 'The Ride' easier.

Hahaha. I highly doubt it was tuned to Cb on purpose.

Could it be an M&M TU-400? Just kidding.

I'm not. Preeety sure that's what it is.

The good news is that it can be cut here and there and, with careful mouthpiece selection and a little pushing and pulling, made manageable. Never going to be a great or even a good instrument, but it can be useful for certain limited purposes. I have one passing through my life just now, in order to learn C fingerings cheaply. I'm going to perform at least a portion of a concert on Sunday afternoon with it, then I think I'll check that box for the time being.

Well.... It DOES have four rotors, what looks to be a straight bell, and a variety of tuning slides.

Some repair guy ought to start the bidding at $225 just for the parts!

Hey kids!! here are those parts to add 4th and 5th valves to some of those surplus high school 'beaters'. A hacksaw and some JB Weld and you could have some pretty snazzy horns!

Instruments tuned in B natural are not that unusual i.e. http://www.amati.cz/produkty/b-tuby-cylindrove/" target="_blank. There are some different traditions out there in terms of tuning, but I would not go so far as to say that this instrument is rare.

Now that I look at it a little closer, it might be an Amati/Cerveny CBB 481-4.

I thought that European 'B Tuba's' were still in Bb?!

Yep, that's the instrument the Jinbao/M&M is "inspired" by. But the Cerveny has the lead pipe enter the first valve straight on, from the top. The clone enters at an angle, as this one does.

So will a BBb sousaphone without a bell.

Followed up on that and turns out I'm wrong. When you switch to English it all goes back to normal. Collecting old instruments in Europe I have tried a few odd key signature instruments and even have a Lidl oval that plays in B natural.
Looks like it's time to find out where the hole is. Funny how cultural terminology can screw a guy up.

Just like my grandma used to say ; "One man's B natural is another man's C flat"

German B = Bb, German H = B natural

I sometimes run across this in trumpet and horn parts; e.g., Brahms Symphony No. 2, second movement.

Maybe that person just plays flat?
If so, I have a Bbb# tuba

..... IT would be a good deal for the raw parts in the valveset (cimbasso parts, etc...?), except for the fact that the #1 and #4 rotors have those 45 degree angle exit ports.

I emailed the seller. He apparently knows the horn is 'C flat' but doesn't have a clue about the bore size or the condition of the rotors. Go figure.

Hey, if it's better than the local brass tech's work...

Bore size (assuming I've identified it correctly and that they're all the same) is .708 (18mm).

Against my better judgement... I received this horn today. After all... parts is parts!

Anyway... the bore measures around .705" and the bell is about 15". About the intonation... I don't have a clue where the knucklehead got the idea the horn was Cb! ... I think the seller needs to either check the 'A equals' settings or buy a new tuner because this horn is a solid CC tuba with the normal sharp 1st valve F. Except for some 'clattery' linkages from lack of lubrication and proper adjustment... this horn is a pretty good one and will make someone a very good '1st CC' tuba.
