| Contd. -3- R4/C20.4.21. I should be very pleased to see specimens of the new switchbox with the new type of accumulator switch, and as soon as this can be purchased not one of the old ones should be fitted, and as quickly as possible we should make the change on all existing cars to this improved type, fitting the spring to give and control the tension of the belt at the same time. In conclusion, the items to fit promptly to new and existing cars are, switchbox with really good accumulator switch and fuse, spring tension of dynamo belt. R.{Sir Henry Royce} | ||
