| 1044 836 Rm{William Robotham - Chief Engineer}9/R.{Sir Henry Royce} 2nd December, 1937. C.H. Brooks, Esq., The Light Production Co.,Ltd., 60/66, Rochester Row, S.W.1. Dear Mr. Brooks, As you probably know, for some time past we have been experimenting with Nelson Bohnalite Auto-thermic pistons. We have also been improving our own piston with regard to reducing its mechanical losses, and getting down the cost of production. We have now reached the stage where, owing to the fact that all the pistons we are testing seem to be about equally satisfactory, our main consideration in deciding which to use has become one of price. As you possibly know the Nelson Bohn people have quoted us a figure which is little more than 60% of the price we are at present paying Light Production. Before we decide to make any change, we should like to have the opportunity of talking with you regarding price, if this can be arranged. Yours sincerely, | ||
