| to OG/MM. from EV.{Ivan Evernden - coachwork} X7800 EV{Ivan Evernden - coachwork}4/22.11.28. copy to HS.{Lord Ernest Hives - Chair} BY.{R.W. Bailey - Chief Engineer} RE LAMPS . 18.EX. X7800 Hs{Lord Ernest Hives - Chair} We have so far not instructed a two way switch for the Three Lamp Scheme which we have now decided to use on this car since the Dipping Lucas P.100. Lamps are not forthcoming in the time. Would you kindly find out from Hs.{Lord Ernest Hives - Chair},prefferably by phone whether he has a Bosch switch, and if he wants one ,arrange to get him one. The Dipping P.100. Lamps will be used on the first car available after their arrival. Messrs Lucas promised us a drawing shewing what the control on the lamp would be like so that we could design our controls, but so far we have not heard a word from them. As far as I can see the first three cars will have to have the three lamp scheme. EV.{Ivan Evernden - coachwork} | ||
