Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}4/KT.20.5.31. RADIATOR FOR 25-EX. 10,000 MILES TEST CAR. We want to build up a radiator for 25-EX. of the small hexagon copper American tubes. As we have only 1100 of these tubes left, we shall have to convert the radiator we have been testing on 19-EX. Will you please, therefore, dismantle this radiator, add the necessary 1" to the matrix height. It should then be built up with a top and bottom tank to suit 25-EX. 25-EX. existing radiator can be transferred to production if they will have it.
