| 1109 To Roy{Sir Henry Royce}/Sanders. from Rm{William Robotham - Chief Engineer}/Wym.{G. Harold Whyman - Experimental Manager} Rm{William Robotham - Chief Engineer}/Wym.{G. Harold Whyman - Experimental Manager}2/ET.24.11.40. With reference to the attached letter re non-skid chains, we suggest that, for the 7.00 x 17 tyres, a pair of ladder type chains will do, as they are only for use on our lorry, and for the 7.00 x 16 size, we are unable under present conditions to send a car to the Parsons Chains Co., but we can send a wheel and tyre complete.
