| R.R. 235 B 20(T) (S.F. 674. 22-5-19) G.{Mr Griffiths - Chief Accountant / Mr Gnapp} 2876. Contd. -2- R1/G6.12.19. ratio which can be modified for any reasonable indicator being fitted to the car. My own impression of the advantages is so great that it will facilitate manufacture to an extent as to compensate for the delay involved. R.{Sir Henry Royce} | ||
