I have seen a Kruspe tuba with 6 valves for sale on ebay and discussed on this site. I believe that they called it a double tuba in BBb and F, so I guess you could consider it a 6 valved F tuba with a BBb side, rather than a BBb tuba. Alexander also makes a double tuba in F & C or F & B with 6 valves, but again, that's not a pure CC or BBb tuba.
