| R.R. 235A (100 T) (S.H. 79S. 10-12-20) G 2947 Contd. -3- EPCS/T7.10.21. proposition for the Goshawk. The Smith machine is, of course, quite out of the question. The Rotax is passably fair. The C.A.V. machine we have not yet received, but according to the makers statements, it will very easily comply with our specification, and that on the single field winding third brush control system. The net quantity price quoted by Messrs. Lucas for this dynamo less coupling at driving end supplied by us, is £8.10.0d. EPC. | ||
