| BY.{R.W. Bailey - Chief Engineer} FROM DA.{Bernard Day - Chassis Design} Copy to SC. Copy to HS.{Lord Ernest Hives - Chair} ORIGINAL DA{Bernard Day - Chassis Design}1/M20.7.31. 85250. 20/25. RADIATOR. Herewith we send N. scheme 3313. shewing the revision of the dropped radiator which R.{Sir Henry Royce} desires as a result of inspecting the model. Instead of the original 5" depth of the matrix below the top of the frame as instructed from the model, it has now been reduced to 4". We understand that the water pipe was criticised and send an alternative proposal reducing the number of bends. We had also intended to increase the centres of suspension from 10" to 10.15", but it is now agreed that this is unnecessary, and though it is shewn on the drawing it need not be followed, but the present centres maintained, the bottom tank being slightly modified to suit.
