| To R. {Sir Henry Royce} from Hs. {Lord Ernest Hives - Chair} c. to BJ. Wor. {Arthur Wormald - General Works Manager} c. to RG. {Mr Rowledge} E. {Mr Elliott - Chief Engineer} c. to DA. {Bernard Day - Chassis Design} BY. {R.W. Bailey - Chief Engineer} X5820 Hsl/LG21.4.27. 20 HP. WHEELS AND TYRES. X4050 With reference to your request that we should try and obtain wheels with smaller dia. rims for the 20 HP. Attached is a letter we have received from The Dunlop Co. Considering that we hit the ground with the petrol tank at Le Canadel(Henry Royce's French residence) with 21" rims 5¼" tyres, we consider it will not be safe for us to sacrifice any clearance.
