Mr. Basil Johnson, Rolls-Royce Limited, 14-15 Conduit Street, London W-1, ENGLAND. Att. Mr. Hives - Derby Re: Perfect Circle Piston Rings Dear Sir, On September 9th last, you told me that you were on the point of standardizing one Perfect Circle Piston Ring in the lowest ring groove on the piston. I would like to ask whether it is your intention, when standardizing this ring, to cancel the L section rings which have been in use and to substitute the standard rectangular section rings in their stead. Yours faithfully, Thos. Nadin. TN/B RECEIVED STAMP: OCT 21 1927 HANDWRITTEN: X741 | ||
