X3398 PETO & RADFORD, 50, GROSVENOR GARDENS, LONDON, S.W.1. M/C.272 27th Feb. 1923. Messrs. Rolls-Royce Ltd., Nightingale Road, Derby. X.3398 X 4414 P Dear Sirs, In reply to your letter of the 22nd. inst. EFC1/T. re T.B.D.7. batteries for 20 h.p. car and your remarks re the six compartment moulded box, we may say the really extraordinary success of our moulded three compartment boxes during the last two years, and the desire expressed by several customers for a 12 volt set decided us to make the tools for a six compartment box, the moulding of which we have every reason to believe will prove just as successful. With regard to the advantages of the single moulding over the type with six separate cells, these strike us as being:- 1. A saving in cost. 2. Elimination of the wood box which sooner or later gets acid on it and rots and eventually comes to bits. 3. A stronger job. 4. Even less liability to leak owing to the thicker walls, etc. 5. Much greater accuracy in outside dimensions than that obtained with wooden boxes. 6. More accurate cell to cell dimensions; with six separate boxes, these always vary a bit. 7. A nicer looking job! These advantages have been found with our moulded three compartment boxes and we think it fair to assume that a six compartment box will posses them also. contd. | ||
