Air-Britain Aeromilitaria 2005-02 / Out of the Archives

The article on Martin-Baker Aircraft in the previous edition of Aviation World did not allow space for drawings, so a copy of a drawing of the projected M.B.4 is reproduced in this issue of Aeromilitaria. It is believed that this drawing, found in The National Archives at Kew, has never been published before - it shows the Rolls-Royce Griffon-powered fighter prototype (intended to be R2496), which was of similar lines to the M.B.3 (R2492) apart from the change of engine from the Napier Sabre fitted to the M.B.3. The M.B.4 was extensively modified during construction and later appeared as the Griffon-powered M.B.5.
