FLIGHT, NOVEMBER 20, 1931 THE INDUSTRY Stormgard Weatherwear AN interesting development and addition to the tradeof Leeds has been made by A. Whyman, Ltd., the manu- facturers of the well-known Stormgard Weatherwear. Acontract for a special type of clothing has recently been placed by the Air Ministry with this firm, and it is thefirst time that this special class of work has ever been placed in Leeds. Further inquiries concerning this firm'sspecial productions are not only being received from all parts of the world, but several foreign Governments havemade inquiries for further details. Luxor Goggles for Holland E. B. MEYROWITZ, LTD., of 199, Regent Street, W.I,manufacturers of the world famous Luxor Goggles, have just received a large contract from the Military Departmentof the Dutch Government of Amsterdam, and they are using the new No. 10 model exclusively. This is thesecond large order Meyrowitz have had for this model from the same source, and they are looking forward toother contracts from the various Governments throughout Europe.Rotax Electrical Equipment AN interesting catalogue has recently been issued andcan be procured for the asking, of a special lightweight electrical equipment for light aeroplanes by Rotax, Ltd.,Willesden Junction, N.W.10. The sales department is under the close supervision and guidance of Mr. E. Pearce,who will be pleased to hear from any FLIGHT readerinterested in this subject. " Petro-Flex " HOBDELL, WAY & Co., LTD., of 20, St. Clare Street,E.I, the manufacturers of the well-known " Petro-Flex " tubing, have just issued a leaflet illustrating some of thefamous users of " Petro-Flex " tubing, and also giving instructions—in English, German and Spanish—for fittingthis tubing. Copies of this leaflet can be supplied to any member of the trade who is interested.Vacuum Mobiloil IN last week's issue, through a slip of the pen, thelubricating oil used in Mr. Butler's record flight to Australia was given as Mobile Oil ; it should be understood thecorrect title of this oil is Vacuum Mobiloil. The " Graphic " African Airways Number PUBLISHED on November 14, the Graphic African Air-ways number forms an exceptionally interesting encyclo- pedia of Africa and African conditions, particularly as theyapply to aircraft operation. This number contains a wealth of valuable information, is, of course, plentifully illus-trated in the usual Graphic style, and has many well written articles of African interest. A coloured centrespread painted by W. E. Johns shows Alexandria with two Short " Kent " flying boats of Imperial Airways arrivingthere, and might well have been called a study in " Mediterranean Blue." A cheerful and encouraging noteis lent by the fact that the same issue contains illustrations and a report of the opening of the present Parliament, onwhose constructive handling of the tariff question depends the immediate future of aviation to such a large extent.Miss Lippens's " Professor " Sailplane AN unique opportunity has arisen to buy a " Pro-fessor " sailplane complete with trailer of the most up-to- date pattern. It was on this machine that Miss Lippensmade the world's duration record for women. Miss Lippens would like to sell her machine in view of the difficulties oftaking it back to Belgium. She is over here for a brief holiday, and is anxious to dispose of the machine at areasonable price, but should she fail to sell it she will take it back with her. The machine is being looked afterwith the Channel Club's machines close to Folkestone, and arrangements can be made to see it. Miss Lippens realisesthat in the present depressed state of affairs people have little money to spend, so she is willing to accept a veryreduced price for her machine and trailer, which cost over £225. The price asked is £150, but any reasonable offerwill be considered. Three or four pilots might well club together to buy this machine which has such an outstandingrecord to its credit. Inquiries should be addressed to Miss Lippens, care of The British Gliding Association, 44a,Dover Street, W.I. Accessories BROWN BROS., of Great Eastern Street, London, E.C.2,are taking an increasing interest in aircraft accessories, and their monthly journal (which will be sent to those in theaircraft trade who write mentioning FLIGHT) now has anarticle devoted to aircraft instruments by A. Hessell Tiltman which is of great interest. PUBLICATIONS RECEIVED Jahrbuch 1931 der Seutschen Versuchsanstalt fur Luft-fahrt. E.V. Edited by Dr.-Ing. W. Hoff. R. Olden- bourg, Munich. Price M. 62.
