| Hs {Lord Ernest Hives - Chair} X 577 O. {Mr Oldham} IE 380 To Hs. {Lord Ernest Hives - Chair} from Sg. {Arthur F. Sidgreaves - MD} Copy to Mr. E. {Mr Elliott - Chief Engineer} [struck through] By Day [struck through] re 20/25. SgE/MJO.12.31 Referring to Hs {Lord Ernest Hives - Chair} /Rml/MA.22.12.31 and Hs {Lord Ernest Hives - Chair} 1/MJ.28.12.31 I quite agree that, when 18-G-4 goes back to France, it should have the modifications which you are suggesting for the Continental 20/25 embodied in the engine and thus give us an opportunity of proving the parts out. If, as I assume, you are also proposing 18" diameter road wheels and higher ratio axle for the Continental type, then I agree that these should be fitted as well. When E. {Mr Elliott - Chief Engineer} was here yesterday, he expressed doubt as to whether this engine would be satisfactory with 6.1 compression ratio, and I understand he will be going into this with you when at Derby.
