| X 1435. C O P Y. Letter from: Chalas and Sons Ltd., Finsbury Pavement House, Moorgate, E.C.2. To: Rolls-Royce Ltd., Conduit Street, W.1. 28th November 1929. Dear Sirs, Referring to your letter of the 2nd inst., Ref. Py10/Av/JL 2929, we shall be glad to hear whether you have received any reply from your Works at Derby concerning Ethylebe Glycol (Prestone). We should like to advise you that we have arranged to keep a stock now in London of gallon cans of this product and for this parcel we are making specially reduced price of 11/2d per gallon ex warehouse, London, which price includes duty. We shall be glad to hear whether your Derby Works would be interested in taking over a small consignment of these cans, and confirm that we shall be only too pleased to give them any further particulars they may require on their use. We are, of course, quite aware that other anti-freeze products are being offered in this country, at lower prices but we should like to advise you that anti-freeze products should not be compared on a price to price basis only. In America cheaper anti-freeze products exist this does not alter the fact that Prestone is preferred by everybody and vast quantities are being sold there per annum. We give you below a few of the reasons why Prestone should not be compared on a price to price basis only, and trust that you will take this into consideration:- 1. The vapours given off by Prestone are non-inflammable. 2. Prestone does not corrode any of the metals used, and has no effect on soldered joints etc. 3. As Prestone does not materially raise the boiling point of water the temperature of the engine is kept approximately the same as when water alone is used. 4. A further point here is that Prestone is not viscuous and there is therefore no danger of over-heating due to improper circulation of the cooling system. | ||
