The Humber Motor Company Ltd. manufactured a British version of the Bleriot XI in 1910, known as the Humber-Bleriot Monoplane. At the 1910 Olympia Aero Show Humber exhibited a single-seat monoplane designed by aviator Hubert Le Blon. Powered by a three-cylinder Humber engine, it had variable-camber wings and a small diameter tapering wooden boom served as the fuselage. Two further Bleriot modifications were built to the design of Captain T. T. Lovelace, and two Roger Sommer biplanes were completed towards the end of 1910. One of the latter carried the first official air mail in India.
