I purchased a Besson Bb 3 valve compensating tuba for $600. I think I did okay with that, it has the usual bash from past tip overs. But it's not unplayable, it's built like a tank, and the compensating tubes makes it a great "set and play" kind of horn. My first horn in that style. It does has a stuffiness with the compo set up, that can be overcome with practice.
The Bell reads "Made In England" "Besson" and "50 medals of honor", no mention of B&H, just an English Tuba. It still has "sack splitter" knob on the bottom, rare to see those, and it has a small shank receiver. A regular mouthpiece goes in about an 1/8 of an inch.
Serial Number 477XXX
I have looked at different sites and get different results, does anyone here have one of these to share their ideas about these horns. But I am guessing about 1978 for its date of manufacture.
I wrote it off at first glance as a student horn, after all, there isn't enough tubing! (LOL) I stand differently after playing it, as it gave me a hernia!

I still love my CBB-681, and for community band, it's a great horn, thought I'd keep this Besson as a temp when the Cerveny needs care. Thank you all for your time and wish you all much luck and sonorous tones!
