| To EFC. from R.{Sir Henry Royce} C -2- RL/G12219 Contd. timer gap .020" = .5 m/m wearing away to .025" = .6 m/m; Then let us do all to prove this right, and make a sound job of constructing 2000 sets, 1500 for current cars and 500 converts for repair cars coming in to have electric starters fitted. Transfer your experimenting to starter or lighting sets or to the new ignition for the 20 H.P. I will send you some calculations to make. R.{Sir Henry Royce} C [Handwritten] FHR read | ||
