| Roy{Sir Henry Royce} from EFC. c. Hs{Lord Ernest Hives - Chair}/AJL. X.4477 EFC2/T5.4.29. With regard to the attached, the four bulbs in question are special double filament bulbs which according to statements of both G.E. Co. and Lucas, are in the experimental stage. These bulbs are being carefully watched for performance in the Lucas P.100 head lamps and we are prepared to inform both Messrs. Lucas and G.E. Co. of results achieved by them. In the circumstances, I think it could suitably be put to Messrs. Lucas that they should withdraw their invoice. If they show any signs of disagreement then I think the matter should not be pressed, but held in abeyance until we see what results the bulbs give. EFC. | ||
