| -2- Messrs. Rolls Royce Ltd. Aerolite Pistons for you to test, but subsequent production was changed over to RR.53. We feel you would not wish to test Pistons in an alloy which would not subsequently be used for production, and would be glad therefore to have your decision as to whether you wish us to make the experimental Pistons in our alloy or the one called for upon your drawing. Yours faithfully, FOR THE LIGHT PRODUCTION CO. LTD. C.N. Brooks GENERAL MANAGER. [Upside down watermark text: PARCHMENT TUB-SIZED "NOMAD"] | ||
