COPY. X766. To Hs.{Lord Ernest Hives - Chair} From Sg.{Arthur F. Sidgreaves - MD} c. to Wor.{Arthur Wormald - General Works Manager} E.{Mr Elliott - Chief Engineer} c. to Da.{Bernard Day - Chassis Design} BY.{R.W. Bailey - Chief Engineer} re. Phantom - cooling. Sg{Arthur F. Sidgreaves - MD}9/E16.9.30. X.766. X.7250. In your Hs.{Lord Ernest Hives - Chair}2/MJ.9.9.30. you mentioned that soon after we had despatched a few Phantom ll cars, we got into very serious trouble with radiators becoming stopped up. I was surprised to hear this because, whilst radiators becoming stopped up was a very serious trouble with Phantom l's, it was news to me that it was a trouble with Phantom ll's, and on making enquiries I cannot find confirmation that it was a Phantom ll trouble. However, whether that is so or not, I gather it is quite correct that, since the first Phantom ll's came out, an alteration has been made to the radiator tubes which has had the effect of making the average temperatures 8°C. hotter than originally. This certainly is unfortunate as our margin of safety has always been on the fine side. When R.{Sir Henry Royce} was here on Friday last I spoke to him about this matter and he places great reliance on the square tubed radiator. In conversation I gathered that the first one which was made was not in accordance with his intentions and I understand that another one is now in hand. It seems important that this should be pushed on with as rapidly as possible. Sg.{Arthur F. Sidgreaves - MD} | ||
