| 309u To Rm.{William Robotham - Chief Engineer} from Sg.{Arthur F. Sidgreaves - MD} re P.III. Sg{Arthur F. Sidgreaves - MD}16/Ell.11.36 The points I made a note about yesterday that apparently want 10/15,000 miles testing were as follows: New type exhaust system. Improved bearings. The new type four port cylinder head. Modified stays behind the radiator. Rubber shackles as compared with non-rubber shackles on the same car under the same conditions. Brico cylinder liners. Under bonnet temperature modifications and thermostatic control. Also the question of doing away with hydraulic tappets. I understand that you will let us have a complete list with information as to what car will go and approximately when. Sg.{Arthur F. Sidgreaves - MD} | ||
