FLIGHT, NOVEMBER 27, 1931 - CORRESPONDENCE The Editor does not hold himself responsible for opinions expressed by correspondents. The names and addresses ofthe writers, not necessarily for publication, must in all cases accompany letters intended for insertion in these columns. R1OO [2779] I have just read in the daily Press that R.100is now definitely bold, and is to be broken up for " scrap " (apart from the engine, which remains in the Government'skeeping). May I suggest that some air-minded person buys thenavigational and other instruments and presents them to, say, the Koyal Aeronautical Society, that is, if the saidSociety has not already thought of taking this step. It would at any rate keep part of R.100 " in the family,"so to speak, instead of letting them go to someone who would only regard them as curiosities, instead of lookingupon them as emblems of what has been and of what might yet be. The only remark one can make on thedismantling of Great Britain's sole remaining airship is " A Dius . . . Quien sabe? " I only regret that I myself am unable to carry out theabove suggestion, which, should it come to pass, I hope will be appreciated by all sometime airship officers andcrews. Hail and farewell, R.100! Wembley Park, Middlesex. MARY KNIGHTLEY. November 17, 1931. POBJOY ENGINE PARTS F2780] May I be permitted to reply to the letter pub-lished in this week's issue of FLIGHT, from Mr. T. A.Dennis, of Messrs. A.B.C. Motors, Ltd., with reference to " Pobjoy Engine Parts." In order that the claims madeby Mr. T. A. Dennis may thoroughly be assessed by your readers, I feel ihat an explanation from The MollartEngineering Co. is necessary, so that the actual position may be gauged. The first 45 cylinder barrels, including those for theall-important type-test engine (which came through with flying colours) were completely machined throughout fromthe forgings (not castings as stated by Mr. Dennis) by my company. In order to increase the output of Pobjoyengine components, and to facilitate the design and manu- facture of the crankcase jigs, fixtures and gauges which we had on hand, we agreed to Messrs. A.B.C. Motors, Ltd.,doing certain machining operations on the cylinder barrels (as a temporary measure) which are as follow: —Turn,screw, and form outside, and bore the cylinder barrels. We then completed the machining operations, which areas follow:—Rough and finish hone all bores, screw the cylinder barrel on to the head (using the Pobjoy patentclamping ring), drill and spot face bolt holes, machine square flange on cylinder barrel foot, mill rod clearances,drill and ream holes for valve rocker brackets. I feel all engineers will be able to assess the relativeimportance of the operations carried out by Messrs. A.B.C. Motors, Ltd., and my company respectively, andwhilst not wishing in any way to detract from the good work carried out by my friend Mr. T. A. Dennis, I feelthat neither your mention of my company's name under the heading of " Butler's Flight to Australia," nor ourpaid advertisement, overstated our claim, and in conclusive proof of the above I quote the designer's opinion whenhe writes as follows : — Mth June, 1931.—" We should like to express ourappreciation of the exceptional good finish and accuracy of the various parts you have, supplied us for our aeroengines. " We feel confident that the remarkable power outputobtained from these engines without prolonged running in, the freedom from gas leaks and cylinder distortion, andthe low oil consumption of the engines, may be entirely attributed to the accuracy and precision with ivhich thecylinder bores are finished, the valve seats inserted in the heads and the heads screwed on the barrels. " The accuracy of the pistons also contributed to thegratifying results." This testimonial from Mr. Pobjoy, who has proved him-self one of our leading aero-engine designers, definitely " Renders unto Caesar that which is Caesar's," and can beseen at any time at our works. THE MOLLART ENGINEERING CO.,Thames Ditton, Surrey, A. J. MOLLART.November 21, 1931. R.A.F. RUGBY FOOTBALL Cranwell versus Royal Military Academy, Woolwich From a Correspondent) Result:—Cranwell 14, Woolwich, 5ON Saturday, November 14, the Koyal Air Force College played the Royal Military Academy atCranwell. The result of this match was expected with some interest, as Cranwell the previous weeksuffered defeat at the hands of Sandhurst, whom Woolwich have yet to play.The game was played under good conditions, the turf being firm. There was no sun and only a moderate wind.A great number of spectators assembled and followed every movement of an open and exciting game. The game opened with some very fast work among theWoolwich threes. It was clear that they were a good deal faster than their opponents. Also, their forwardswere heavier and were cleverer at getting the ball back to Lewin, who played a skilful fame at the base of thescrum. But the handling of the Woolwich wings was their weak point ; and this, combined with the bettertackling of Cranwell, who had taken to heart the lessons of the Sandhurst match of a week before, kept the scoredown. But after about twenty minutes' play the Wool- wich attack would not be denied. They again got theball cleanly out, passed it along their line of threes, and Winchester, their captain, getting well into position, tooka pass and scored near the posts. The try was converted. This was to be the only Woolwich score. Cranwell, who had for various reasons turned out ateam which was largely experimental, now got together, and gradually assumed the offensive, though the scoreremained unaltered at half-time. After half-time, Cranwell playing with the wind, con-tinued their attack, and never dropped it till the end of the game. A few minutes after the start, Collyns, a flightcadet from New Zealand, who played a fine winging game throughout, and who should get into first-class football,scored far out a try which was not converted. Cranwell were soon on the attack again. From a line-out Prowsegot the ball and carried it deeply into the Woolwich 25 till he was brought down by Sykes, the Woolwich fullback, who played a gallant game throughout. Then Gold- ing, a versatile player, who represented the Public Schoolsat scrum half before he came to Cranwell, after a long bout of individual dribbling, picked up cleverly, and ran inunder the Woolwich posts for a try, which again was unconverted. A few minutes later Prowse, from a crosskick by Doran, scored again for Cranwell. The score was now 9—5 in favour of Cranwell, a dangerous score, forWoolwich had only to score a goal to be one point ahead. The old moral about the importance of place kicking isobvious. However, Cranwell consolidated their position despite a desperate Woolwich offensive, when Parselleran over with a clever swerve on the blind side of the scrum. About this kick Eisner made no mistake. Therewas no relaxation by either side during the last keen minutes of the game, but also no further score ; thusCranwell were left the victors by 14 points (3 tries and a goal) to 5 (a goal). For Cranwell, Eisner and Leigh wereoutstanding, the latter playing with great courage and determination. Of the forwards, Collyns and Rhys wereprobably best. Of the " shop " team, Winchester, their captain, led his forwards pluckily, Sykes was reliable atfull back, and Lewin was very clever behind the scrum. The thanks of both sides are due to the exemplar 'refereeing of Mr. Bott. 1180
