| To BY.{R.W. Bailey - Chief Engineer} from R.{Sir Henry Royce} c. to Hs.{Lord Ernest Hives - Chair} 40/250 RL/M1 7. 7. 25. RE. RADIATORS, BONNET SHUTTERS & LOUVRES. X. 8250 X. 8240 We are perfectly contented with 'V' series radiator simply raised 1", or we are contented with a parallel radiator the 1" higher with integral shutters. Regarding shutters these can be either integral or added. We think integral should be the better. DA.{Bernard Day - Chassis Design} will send particulars of experimental radiators later. We so far do not like the appearance of the taper radiator. We do not like the appearance of the louvres on 7-EX. I should use shutters until we get a better design and system of making. I understand Sales have asked for finer pitch louvres, which please make. EV.{Ivan Evernden - coachwork} says those on 7-EX were not level with the ground at the top - (i.e. were higher towards the dash), and gave an appearance that the hinge was lower at the dashboard end.
