GOLD WILLIAM PETO F.C. GRAHAM MENZIES C.R.D. PRITCHETT G.R.N. MINCHIN T.W. PRITCHETT YOUR REF. OUR REF M/5 X.3889. 19th June 1926. Messrs. Rolls Royce Ltd., DERBY. For the attention of Mr. Fowler Clark Dear Sirs, We thank you for yours of the 18th inst. and note that you are going to carry out tests on the charging P.D's. We think it rather unlikely that you have got in your laboratory any of our latest batteries with the lowered P.D. and when your tests commence we should like to see that the battery of ours under consideration is of the latest type. These have only just barely begun to get through in production. X5889 With regard to the special cells, we are making up four as you suggest, two of each construction, and will invoice them to you on your order for the price of three, as you suggest. Two of these will be of the latest type with the lowered P.D. and other features and the other two will be very near the type previously used where the P.D. is rather high. The reason of our wishing you to test them in this way is that you should confirm our results that the steps we have taken to lower the P.D. do not in any way affect the life. Yours faithfully, PETO & RADFORD. GRMinchin | ||
