FEBRUARY 24, 1921 A NEW K.L.G. PLUG AND A ROVER CAR FOR A GUESS AT this period of time it is unnecessary to recall how Mr. Kenelm Lee Guinness was called back from fighting the enemy on the high seas to make plugs to deal with the said enemy more effectively in the air. It is sufficient to say that the success of K.L.G. plugs continues mainly as a result of the fact that the makers, the Robinhood Engineering Works, Ltd., have never been content to rest on their laurels, but are continually at work to improve their product. It is well known, although the fact is often overlooked, that a plug which has been designed for use with one type of engine will not function properly in another mainly because of the variation in the internal conditions. "Phis coupled with the any danger of " seizing," while the centre electrode is wrappedwith ruby mica, placed in position under great pressure and then highly polished. The plug is made in five types to suitpractically all models of Rritis-h, Continental and American cars, and the price is 6s. each, while the centres are sold at3s. each. With regard to the competition it may be said that the first prize—a 1921 model 8 h.p. Rover car, value ^300, will be awarded to the purchaser of a K.L.G. plug who correctly .estimates or most nearly estimates, the number of K.L.G. plugs sold under the special scheme by Messrs. S. Smith and Sons during the periods February 21 to March 7, inclusive. The K.L.G. plug. The 8 h.p. Rover car which forms the first prize in the K.L.G. competition. research work which is always going on in the K.L.G. laboratory accounts for the advent of the new " G " detach- able K.L.G. plug for car work, to introduce which Messrs. S. Smith and Sons (MA.), Ltd., the selling agents, of 179- 185, Great Portland Street, W. 1, have organised a com- petition, some details of which are given below. One of the main features of the new " G " plug is the detachable centre. The idea is that the body of the plug remains in its place in the cylinder and when the plug requires attention or replacement the centre, by removing the gland- nut, may be taken out and cleaned, or, if necessary, replaced by a new centre. The centres are being placed on the market separately with this object. The body of the plug and the gland-nut are treated by a special method claimed to render them rustproof and obviating The second prize, for the next nearest estimate, will be a 4 h.p. Triumph roadster, value £127 10s. and the third, a 2J h.p. Enfield two-stroke, value £65. There will also be six prizes in the shape of Smith bezel-wind mantel-piece clocks, in mahogany or oak, value £6 10s. each, and fifty consolation prizes of motor accessories value one guinea each. The plugs may be purchased from a local dealer, or, if he has no stock, direct from S. Smith and Sons, and an estimate must be written on the form which will be found in the box ; when it has been completed it must be sent to 179-185, Great Portland Street, W. 1. In the event of a tie the first estimate opened will count for the prize, and no person may take more than one prize. There are also a number of prizes for dealers in addition to the above. First All-Japanese Air Race RECENTLY the first all-Japanese air race was flown over a course of 400 miles. Seven machines were entered, and the winner of the race was Ishibashi on a Spad, with Hispano- Suiza engine. His time over the course was 3 hours 27 irins. Presumably this Spad was built under licence, as the race was for Japanese-built machines. Progress in Peru A NATIONAL aeronautical company was founded for commercial aviation in Peru as far back as July last year by Lieut. Lloyd Moore, one of the crew of the "N.C.3," "ir. A. E. Russell, and Capt. M. A. Mott, an experienced American war pilot. This organisation appears to have done well up to the present, and possesses nine 'planes at its aerodrome at Bellavista, with an additional machine due to arrive shortly. A number ol pupils have already been enrolled and drafted off with their licences as C.N.A. Pilots, one of these pupils, Mr. Herbert Tweddle, recently completing the flight of about 700 miles from Lima along the Peruvian coast to Puerto Pizzaro, the most northerly Port of the Republic. The company hope that they will be awe to receive recognition by the F.A.I, for pilots' certifi- cates to be issued by the C.N.A for those who are trained under their segis. .»••.--, The bulk of the C.N.A. flying traffic up to the present has been south of Lima to the comparatively thickly popu- lated agricultural areas of the Province of lea. Flights to the various haciendas and towns in this section are effected in from one to two hours. Overland by motor-car or horse- back the same trip would require a strenuous two or three days. The steamer trip, when a ship is available, requires from one to two days. The machines have been used for the transport of passengers, mail, money, newspapers, spares for machinery, etc. The carriage of newspapers was done as an experiment, and reveals the enormous field open for mail-carrying aeroplanes along the Peruvian coast. Charting the Rockies Air AT Blossburg, on the summit of the Continental Divide, a branch of the Helena, Mont., office of U.S. Weather Bureau is to be established, for observations of air currents and other details which will be used in charting a safe route for aero- planes above and across the Rockies. The Dutch Indies Acquiring Aircraft A NUMBER of D. VII machines from the Fokker factory, fitted with British engines, for use in the Dutch Indies, have been ordered by the Dutch Colonial Department. They have been specially constructed for use in the damp warm climate of that part of the world. 141
