To R.{Sir Henry Royce} from Hy.{Tom Haldenby - Plant Engineer} c. to J.{Mr Johnson W.M.} S 58 N.A. ------ Insulated battery switch on steering column for use with 6 volt coil, worked off either half of the 12 volt lighting battery has been fitted to the above car since it was last with you. This switch has been in use on one of our cars for a month or so now and has given every satisfaction up to the present. I think it is a very desirable fitting and see no reason why it should not be standardised after you have tried it and approved of it. Hy.{Tom Haldenby - Plant Engineer} | ||
