Giant Tuba

The Giant Tuba, was made in the early 20th century by Besson, London. The Giant Tuba has over 34 feet of tubing, weighs 112 pounds, and is nearly 8 feet tall.
The lowest playable note on this open valve instrument is the Bb three octaves below middle C, or the second lowest note on a modern piano (29.14 Hz).
This giant tuba was a London music business landmark for much of the 20th century. It was originally fitted to the wall of the Besson & Co. factory in 198 Euston Road as a shop sign.
The Tuba plays like an open valved instrument as the valves do not move.  It was an outside display piece for the main Boosey & Hawkes Shop in the Edgware Road until 1948 when it moved to the B&H Factory in Edgware, North London.
