Hives, Esq., Rolls Royce Ltd., Nightingale Road, DERBY. Dear Hs.{Lord Ernest Hives - Chair}, With further reference to my letter the other day and with regard to the paper I am endeavouring to write, I wonder whether I could trouble you for some more information. I would like to know the maximum b.h.p. developed per exhaust valve and also square inch of exhaust valve area on the Bentley, 25 h.p. and Phantom car engines. I would, in addition, like to know the b.h.p. developed per valve and square inch of valve area of the latest Kestrel and/or Goshawk when running at their normal rating and when producing maximum power (say, 1000 b.h.p.) on special fuels. I quite appreciate that I am being a nuisance, but I should at the same time be very grateful if you would let me have this information. Yours sincerely, [Handwritten Text] LOV{Mr Lovesey}- Have sent Car particulars H.R. Banks. CAR DATA Ex Area. 1.0"/1.33. Bentley 1.3" Dia Ex. 115 B.H.P. Per ex.
