Looks to me like we have a three valve F and a three valve BBb combined. All of the six principal six valves are useable on both sides and would give lots of possibilities for strange alternate fingerings. When the 4th valve on the left-hand side is depressed enough additional tubing is added to the open F side to make it a BBb length tuba enabling the player to use the right hand valves as a normal BBb.
