| RHC.{R. H. Coverley - Production Engineer} From Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} X777° Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}1/WJ.19.5.30. 19-EX. We do not want to hold 22-EX up for anything except the single point radiator mounting as this is the most important test we have on hand. When we have tried this out we shall do other work on the car. Will you please prepare :- (1) Wider track rear axle. (2) Front shoes to take thicker linings. (3) Unit to take extra oil to the cylinders, and Auto-Klean filter. (4) Larger Bijur pump and centre point lubrication connected to the axles.- for 19-EX. We ought to get two sets of these pieces as we shall fit them to two of our cars. The single point radiator mounting will await the result of the test on 22-EX before a decision is made as to fitting on other cars and the thermostatically operated shutters are going to be re-designed.
