accepted a position on the board as Technical Director. Other than the income from operating commercial flights, the main income between 1919 and 1921 came from selling Channels with a modified design known as the Channel II being developed. As well as sales within Great Britain the company was able to sell 19 overseas, to customers, including Chile, Japan, New Zealand, Norway and Sweden. Schneider Trophy 1919 to 1924 In 1919 Scott-Paine decided to enter an aircraft from Supermarine in the upcoming 1919 Schneider Trophy seaplane race. A suitable aircraft was produced by heavily modifying N61, the youngest of the two Babys that the company had purchased from the government. Fitted with a Napier Lion engine it was given the name Sea Lion. Flown by Basil Hobbs the aircraft sank on 10 September 1919 after it struck flotsam while competing in the event. In early 1920 the company developed the Supermarine Sea King a single seat flying boat fighter resembling the Baby and the contemporary Sea Lion racing aircraft. While the prototype of which was exhibited at the Olympia air show but obtained no sales. This was subsequently fitted with new wings and tail surfaces and fitted with a more powerful engine, which Supermarine designating it as the Sea King II. No sales were however forthcoming. For the 1922 Schneider Trophy contest, which was being held in Naples, Italy, the company modified the Sea King II by increasing the size of the rudder and fin and fitting a more powerful engine which gave a 50 percent increase in power. Designated Sea Lion II the aircraft won the contest and thus stopped the Italians from winning the trophy outright. With it looking likely that no British company would be entering an aircraft in the 1923 Schneider Trophy contest Scott-Paine was persuaded by the British organizers to enter. As Supermarine being in a poor financial state, Mitchell was restricted to modifying the Sea Lion II, the result which was designated Sea Lion III and proved to be uncompetitive. For the 1924 contest Mitchell began design work on a completely new flying-boat biplane design called the Sea Urchin, which would have been fitted with a Rolls-Royce engine. However, there was insufficient time to overcome a number of design issues which lead to Supermarine withdrawing from the event. Bird takes over In the early 1920s the company developed a series of similar one-off amphibians.
