| CJ3/B141212. [Handwritten top center: CA] [Handwritten left margin: X/220/1] 14th, December, 1912. F.H. Royce, Esq., Grand Hôtel du Canadel, le CanadelHenry Royce's French residence, par le Lavandou, Var. My dear F.H.R., I see that the Austin people have brought out a car with enclosed valves, and it seems to me that since they have constructed a 4" engine as standard that we ought to start making a design for a four and a half inch engine with enclosed valves and with as much as possible of the combined gear also enclosed so that it may have a simple exterior.
