Shouldn't you be able to get 4 different keys with only 2 or 3 valves? With 2, you've got 4 combinations of tubing you can switch in or out. With 3 valves, you could have F in the "all open state", then drop either 2, 5, or 7 semitones with each valve used independently, to get Eb, CC, or BBb respectively. So there's at least one extra valve unaccounted for in the e-*** poster's description, IMO.

It could be a big F tuba, with 3 of the "extra" valves set up as proposed above, and the 4th valve as a long semi-tone or some other option for improved intonation somewhere.
