Moving on to something much prettier to the eye we come to another rare bird, the Grahame-White Type 21, a single-place 'Scout' produced in the spring of 1917. In Mr. J. M. Bruce's heavyweight opus British Aeroplane 1914-18 (Putnam, London 1957) I see on page 263 a heavily retouched photograph of the Type 21 which has the 80-h.p. Le Rhone driving a four-blade propeller. Maybe Jack Bruce would like to comment?
