Copy of letter received from:- Messrs.Prices Patent Candle Co.Ltd., Belmont Works, Battersea, London.S.W.11. Ref.- JWGB/VHG. L.M/B. 23rd July, 1930. Messrs.Rolls-Royce Limited, Derby. REF. ROY{Sir Henry Royce}2/MG. Dear Sirs, RE PRICE'S SPECIAL GEAR COMPOUND. With reference to your recent information per telephone that you would like word from us before the end of this week, we have pleasure in advising you that we are sending you a gallon of slightly modified Special Gear Compound. Without impairing the Homogenity of the original quality, we have materially reduced the acidity, and have we think slightly improved the adhesive properties. The water content is no greater than formerly (it is still approximately 0.5%), and there is no noticeable tendency for sludge or other sediment to settle out on standing. We believe, therefore that the stability and equilibrium of the compound is as good, if not better, so taking it all round we frankly think that we have effected an improvement, and one which we think will be noticeable under actual working conditions. We have several gallons prepared, and should the gallon which we are sending you not be sufficient we can immediately on hearing from you, perhaps by telephone tomorrow, send you a further two or three gallons. You will find that we have reduced the quantity of Stockholm Tar, and have introduced a very small proportion of lead oleate. With regard to the gallon which reached us as advised in your letter ref - BY1/G, we find that it is normal for our Special Gear Compound as hitherto supplied, except that the proportion of water has increased to 1.1%. Yours truly, PRICES PATENT CANDLE CO.LTD.(Sgd).J.W.G.Brooker. [Stamp: EXPOSURE No 64 "JUSTSO"] | ||
