By.{R.W. Bailey - Chief Engineer} From Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} ry-50. RADIATORS. Ha/Rm.{William Robotham - Chief Engineer}5/MJ.23.7.31. X.7250. X.5250. You will see from our recent notes that it has been decided to standardise the large diameter American tube. We have handed one of these tubes to By/SS.{S. Smith} in order that he may make a drawing of it. We should then like you to order up a quantity of such tubes for both the 25 HP. and 40/50 radiators. You will of course arrange that the gap on the tubes of the 25 HP. radiator is not too small. We should recommend a gap of 1 1/4 mm., this being approximately the right size.
