| x540 To By.{R.W. Bailey - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls}2/KW.10.9.36. We understand that the spring in calorstat is not being fitted on 'M' series 25/30 HP. radiators, although the Standardisation Sheet incorporating this modification was issued on 17.6.36 and completed 4.9.36. We shall therefore be glad if you will now instruct for this modification to be incorporated. It should also be applied retrospectively to all 25/30 HP. cars.
