•588 FLIGHT, JUNE IO, 1937. case; the year had been a most satisfactory one for car sales. The most important development in the aero-engine pro gramme was the successful launching on a production basis of the Merlin engine, substantia] orders for which had been received from the Air Ministry. The Harrow's Turret IT should, perhaps, be made clear that the H.P. Harrow's turret, as illustrated on page 549 of last week's issue, is of Handley Page design, although the driving mechanism is by Nash and Thompson. A similar turret is fitted in the Harrow's nose. Metal and the Dope Industry AT the annual general meeting of Titanine, Ltd., held re cently, the chairman, Mr. W. H. Ward, said that there had been a considerable increase in their output of both air craft finishes and products supplied for other industries. One of the points on which Mr. Ward touched con cerned a question by a shareholder as to whether the increased use of metal aircraft would affect their business. The posi tion, said Mr. Ward, was that every all-metal machine con structed for military purposes had to be coated both internally and externally. He referred to internal corrosion prevention and to external camouflage finish. They had already sup plied considerable quantities of materials for these purposes.
