Flight, December 1919
The "Type L" Seaplane. (September, 1914)
During the same year, 1914, the first Blackburn biplane made its appearance. This machine was a seaplane designed for the Daily Mail " Circuit of Britain," which was postponed owing to the outbreak
of War. In a general way it resembled the Blackburn monoplanes, but instead of the triangular section body which had characterised the monoplanes, the seaplane had a rectangular section fuselage. As the race was called off, the biplane-seaplane, which was to have been piloted by Mr. Sydney Pickles, did not have an opportunity of showing its capabilities in peaceful competition, but quite early in the War she was modified to carry a machine gun, and hence became known as the "Type L" Seaplane.
This machine was fitted with a Salmson Canton-Unne engine of the water-cooled radial type, the radiators being mounted on the sides of the fuselage. Considering the power loading (over 19 lbs./h.p.), the performance was quite good, and the flight range (445 miles) was rather out of the usual for those days.
