| X 219- To BY. {R.W. Bailey - Chief Engineer} from E. {Mr Elliott - Chief Engineer} c. Sg. {Arthur F. Sidgreaves - MD} Wor. {Arthur Wormald - General Works Manager} HS. {Lord Ernest Hives - Chair} E.1/HP.13.6.32. We send you herewith drawing LeC.3115 showing the cylinder head, valves valve rocker gear, etc for Bensport(Codename for 3 1/2-litre Bentley) and Peregrine(Experimental Bentley car never produced / Aero Engine). Would you please put in hand the necessary detail drawings. The design generally has been approved by R. {Sir Henry Royce} and we are taking a print of this drawing down to West Wittering(Henry Royce's home town) with us today to get it finally passed as regards details. The head shown is for a compression ratio of 6 to 1. We expect to use a lower ratio on the Bensport(Codename for 3 1/2-litre Bentley), but this will not affect the head, as owing to the use of the open type of cylinder crown we can vary the height of the piston.
