FLIGHT, JUNE !!), 1931 THE INDUSTRY Recent K.L.G. Successes PILOT OFFICER J. GRIERSON, who recently flew fromKarachi to Lympne in four days, has sent the following telegram to K.L.G. Plugs, Ltd., of Putney Vale:—" Yourplugs used in Rouge-et Noir Flight Karachi Lympne in four days ten and half hours, flying time fifty-two hours,no cleaning or change made throughout, condition at end perfect although shade temperature on journey up to115 deg., very satisfied this outstanding performance.— XJrierson." Another message comes from Capt. Kennard, winner ofthe Heston-Newcastle air race, stating:—"Again your reputation has been upheld. I won the " Evening WorldTrophy " race in my Klemm Cirrus III fitted with K.L.G. plugs. Not a single miss, a good hot spark, and the restbrought me through. I thank you." Capt. E. W. Percival, who was second, and put up the fastest time of145 m.p.h., also " enthused " about his K.L.G. plugs. <l B. Be L." and " B. SC S." WE are informed by Best & Lloyd, Ltd., of Birming-ham, that they have sold to Messrs. Benton & Stone, Ltd., of Bracebridge Street, Birmingham, that department bftheir business known as the Automatic Products Depart- ment, where for 20 years they have made components andaccessories for the motor car, motor cycle, aircraft and general engineering trades. Mr. Scott on his " Gipsy Moth " THE DO Havilland Aircraft Co., Ltd., have receiveda letter from Mr. C. W. A, Scott, in the course of which he writes: — " It has been my good fortune to complete a task thatI had set myself, but you will understand that I first of all provided myself with the best tools for the work. Inmy cable to you from Port Darwin on arrival in Australia, I wired that ' Gipsy Moth fully justified my expectations.'This was so, for I selected your machine after first proving its worth. I should have been most surprised if I hadbeen let down by the Gipsy I used. In point of fact I did not expect the performance that I got under load carried,and at no time was I in doubt of the issue or at any time labouring under any concern for my machine." " Luxor " Goggles and the Schneider Trophy THE Air Ministry has awarded the contract for gogglesfor the Schneider Trophy Team to Messrs. E. B. Meyrowitz, Ltd., for the third consecutive time. Themodel which will be used this year is the Luxor No. 6, with hand-ground Acetex Safety Glass lenses and thelarge fiat cushions. The members of the team will be supplied also with Crookes B. tinted lenses, which theywill use to overcome excessive glare which they are apt to encounter, especially during the training period. Two Useful Products READERS of FLIGHT will be well aware of the value of the '' Chemico '' Non-flam paint remover called '' Namelolf,'' .but it is quite possible that two of the latest products from this firm have not yet come to their notice. Both of these should be equally useful for aircraft, as for motor cars and other engines, The first is " Chemico " Penetrating Lubricant. This is very high grade lubricant, specially prepared, which penetrates where ordinary oil cannot get, such as between the leaves of springs or in any joints or nuts which are rusted up. These latter can soon be released with a few drops of this lubricant. The second is " Chemico " Flushing Oil, which is infinitely preferable to paraffin for removing traces of petrol-diluted oil, sludge, etc., from the crankcase. It can be used afterwards for •cleaning engine parts, etc., and is also a perfect upper cylinder lubricant. Any of these products can be obtained from The County Chemical Co., Ltd., Chemico Works, Birmingham. Parachuting at Hull IN connection with our paragraph last week about the Hull Air Pageant, we have been asked to correct the statement that Capt. McKenzie made the parachute drop. Capt. McKenzie piloted the machine, but the parachute jump was made by Capt. E. W. Stewart. At the same time, we have been requested to state that there is no truth in the rumour (not published in FLIGHT) that Capt. Stewart has broken his ankle. He is, in fact, in the best of condition, and club secretaries and others interested in parachute descents should communicate direct with Capt. Stewart, at Redcot, St. James's Avenue, Hampton Hill, Middlesex. Capt. Stewart's telephone number is: Molesey 1105.
