PETO & RADFORD Proprietors - Pritchett & Gold and E.P.S. Company Ltd. 50 GROSVENOR GARDENS, LONDON, S.W.1. YOUR REF OUR REF M/5. 11th May, 1936. H.E. West, Esq., Messrs. Rolls-Royce, Ltd., DERBY. Dear Mr. West, You will remember the 40/50 sample battery we supplied with the float device and which you returned to us. This had a faked up lid{A. J. Lidsey} and no initial filling device or means of inserting an hydrometer and I told you we were going to make a proper job of it and we now have done. We have a properly designed lid{A. J. Lidsey} with a separate acid filling plug hole and we are making up the battery again with this lid{A. J. Lidsey} and it will be going back to you quite soon. I shall be very interested to hear how it behaves on a car. In a letter from Mr. Elliott he says that the battery we suggested for the Phantom III with the thinner plates is held up at the moment because it is said to have experimental features in it whereas the Exide is said to be more conventional. The only difference between the two is that the Exide has thicker plates and less acid room and we think that ours should prove better with the thinner plates and more acid but if you do not like it, we can supply exactly the same as what Exide are offering. Actually, I should have said that ours was the more conventional because if you take the batteries that are being made throughout the world to-day, there are more being made with the thinner plates that we are offering you than there are with the thicker plates that Exide are offering. I understand the question of ordering a supply from us is slightly held up on this point and we would like to have your views on it so that we shall know where we are. Do you find that ours is a little better than the Exide on starting? It should be slightly better. | ||
