| GRY{Shadwell Grylls} x200 S/W. Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls} e to Bly.{B. W. Bleaney - Bentley Sales} re - 4¼ litre Bentley. Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls}7/KWIO.2.36 Cx{Major Len W. Cox - Advertising Manager}5/KW12.2.36. With reference to your memo, we would rather have the figures on the proper comparison basis if you could let us have these in due course. We note you do not expect the oil consumption to be any different but should like to know what you find to be the difference in petrol consumption. Re axle ratio, we note that the higher ratio would be an 11/43 not 11/41 and that the 11/43 ratio gives 100 m.p.h. at 4,500 revs. Incidentally the 4,750 revs mentioned in my memo was an error - it should have read 4,500.
