Five uncompensated valves give scope for choice of valve combinations to produce the whole compass with acceptable intonation. With two water-keys. Valve type: 5 Périnet valves. Repair History: The mouthpipe was replaced by previous owner by one of the same length but with a wider bore, original retained with instrument.
General usage of type: The F tuba was the customary model used in British orchestras until the 1950s. The sound would complement 3 narrow-bore trombones. Specific usage history: Possibly Harry Barlow's first model: he took up his appointment as the Hallé Orchestra tubist in 1894 and may have commissioned this instrument from the most prominent maker in Manchester. Latterly converted to E♭ and used by Salford Youth Orchestra (1966-68).
