| To Sg.{Arthur F. Sidgreaves - MD} from Rm.{William Robotham - Chief Engineer} X560 Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}3/KW.18.6.36. GLG-5. Sg.{Arthur F. Sidgreaves - MD}6/E.17.6.36. We fitted the Marles steering to your car, the parts to convert it to a three-speed box, and decarbonised it. We also fitted the latest type of silent tread tyre. The horns were changed because on final test when I personally was driving the car, one of them ceased to function, and we are endeavouring to find out why this was.
