I am informed by Mr. Stent that the crankshaft oil caps made for Eagle(Aero Engine) engines in the States, were slightly altered in design so that they could be die cast. Perhaps it would be as well to apply this move to those on the 20 H.P. engine. We should be much obliged if you would issue instructions for a die cast crankshaft oil cap to be sent to West Wittering(Henry Royce's home town) as a model, for criticism.
