FLIGHT, JDNB 27, 1929 THE WESTLAND "WIDGEON " AND ITS FUTURE THE Westland Aircraft Co., Ltd., of Yeovil, are, we learn, prepared to offer for sale the manufacturing rights of the " Widgeon " light 'plane to any company in a position to carry on in works devoted to production with the advantage of lower overhead costs. In such a sale, construction, rights, drawings, blue-prints, etc., would be included, with a sample machine having an all-metal fuselage. Our readers are quite familiar with this well-designed light 'plane. It has been used extensively by private owners, who have reported upon it always with favour. Flying clubs in South Africa have tried it on the hard conditions of training, and private owners in Australia are amongst its adherents. The only reason that the Westland Aircraft Co. wish to dispose of the rights is owing to a change in their policy. They have had to decide between the " Widgeon " and the new three-engined cabin Westland IV. As they are already so heavily engaged on the production of the Wapitis, they do not feel that they are in a position to manufacture, in addition, both the Westland IV and the " Widgeon " in sufficient numbers. The Westland IV has, in fact, aroused considerable interest, and seems to show that it is filling a decided gap amongst commercial aircraft. Already Imperial Airways have pur- chased one, another has been bought by the Wilson Airways, Ltd., of East Africa, and there are, we understand, a number of other orders on the tapis. So the Westland IV will be manufactured and the Widgeon sold. Altogether a sound proposition, -,V; •*••; m m * . • • The Curtiss-Handley Page Slot Installation REGARDING the description of the Curtiss-Handley Page slot installed in a Curtiss " Seahawk," which we published on p. 481 of our issue for June 13 last, Handley Page, Ltd., inform us that, whilst based on the design information sup- plied by them to the U.S. Bureau of Aeronautics, this sliding type of slot is a patent of theirs, of 1920. Also, it may be noted, they have a similar type of slot installed on the machine they have made for the Guggenheim Competition, and this type was tried on a Bristol Fighter before the link type of mechanism was adopted. Splintex Safety Glass, Ltd. EARL HOWE, C.B.E., performed the official opening of the Splintex Safety Glass, Ltd., new factory on. Monday, June 24, at South Wimbledon, S.W.19. ' K.L.G. Plugs WE are informed that K.L.G. plugs were used in the Cirrus of the Avro " Avian " which reached China from •Croydon recently, flown by Mr. Wen-Lin Chen* Pratt's Introduce Lubricating Oils HAVING regard to the practically limitless resources of oils of the Anglo-American Oil Co., together with their years of experience with and experimenting on the lubricating problem, it is a wonder that Pratt's oils should for so long • have remained off the general oil market. Their new depar- ture, therefore, is not really surprising, and in introducing their new motor oils they with confidence refer users to their world reputation for motor spirit. Moreover, they are taking no chances, as before putting the oils on sale, we understand, they have run off some 20,000,000 miles in testing it on British roads, including by-lanes, rough tracks, up hill and •down dale, on every type of vehicle and engine, from motor- cycle and the small 7 h.p. cars to the heaviest vehicles—a world's record test. The results are to be appreciated in the " finished article." Naturally it is very important that with the present-day highly efficient engine, small or large, lubrication should be studied to obtain the best results, and as with Ethyl spirit the A.A. Co. have helped to advance that efficiency, so with their special oils they are carrying it still a step further, by catering for the requirements of the modern refined engine. One great point is that their supplies are under seal, whether in small or large quantities. Their organisation has already provided that the oils can be obtained from dealers throughout the country. The Westminster " Wag-Tale " IF only to help Westminster Hospital, every citizen should get ready with 6d. to procure a copy of " The West- minster Wag-Tale," which has just been published for helping along the good work of the hospital. 'And there's splendid value in this effort—far and away beyond many of the much-advertised books of commerce. Its pages are crammed •with pictures and literature in lighter vein, and in its up-to- dateness, there is, of course, an aviation skit—by G. Pengelly Kerr. But there, obtain a copy and see for yourselves. Auster, Ltd. THE London establishment of Auster, Ltd., has been vacated by the company, as they have decided to centralise all their manufacture at the Birmingham works. Thischange operated from Monday, June 24 last. All com- munications should now be addressed to Crown Works,Barford Street, Birmingham. .

Jean Assolant, the French pilot, also bromght asuccess for the Scintilla magneto.
