| FROM R. {Sir Henry Royce} HS. {Lord Ernest Hives - Chair} ) (At Le Canadel(Henry Royce's French residence).) REC'D. {John DeLooze - Company Secretary} & DESPATCHED FROM WW. 24.1.28. to BJ. WOR. {Arthur Wormald - General Works Manager} RG. {Mr Rowledge} DA. {Bernard Day - Chassis Design} SUPER SPORTS 20HP. EXHAUST MANIFOLDS AND PIPE. It is understood that on the improved 20HP. (next 10,000 miles) and on Super-sports, these will be on the lines of Sch. 935. but proportionately larger bore. HS {Lord Ernest Hives - Chair} /ACL's memo. of 17/1/28. on the subject, speaks of Sch. 934., and in the diagram it is better than Sch.935., and no explanation of what this is, and why we may not have it. Probably there is some mistake as I understood that for some time we thought type Sch. 935. was the best practical pipe. I sent to E. {Mr Elliott - Chief Engineer} yesterday my sketch of 2 car exhaust pipes like Sch. 935., and also the 3 long ones as used by Mercedes in their sports. R. {Sir Henry Royce} | ||
