Bristol Hydro no.120

The Hydro no.120 was a two seat, single engine biplane configured as a single float seaplane, designed by the Romanian Henri Coanda and built by Bristol in 1913. Begun as a private venture, it was bought subject to acceptance trials by the Admiralty, but it did not last long enough to undertake them and was lost on its first flight. It received no Bristol type name, and as a pre First World War type it was not given a retrospective type number in 1923, so it is usually known by its Bristol construction number. It had a single bay biplane layout, an 80 hp Gnome rotary engine in a close fitting aluminium cowling, a wide mahogany float and two wingtip floats for lateral stability.
