| RR 300 (120B) (SF 349 24-1-19) MP 200552 91302 ROLLS-ROYCE LIMITED. INSTRUCTIONS. To E.F.C. Order No P.A. 74. Customer's No. Re X 3723. April 2.nd 1921 of that machine, after its endurance test, this type of distributor would not be an advantage. The cam-ring also is not of the best design. If the larger of the two machines, the F61, which corresponds to the Booth, was carried through the tests, the results would, I think, be fairly representative of the other two. Signed C.A.P. This Sheet must be filed on completion of the work. | ||
