| To RHC.{R. H. Coverley - Production Engineer} From Hs{Lord Ernest Hives - Chair}/Les.{Ivan A. Leslie} 87250. Hs{Lord Ernest Hives - Chair}/Les.12/MJ.21.8.31. RADIATORS. We require a large tube radiator for 27-EX. The existing radiator can be connected, as we have no further use for the square tubes. As regards the bumper chassis, for this we require a large and a small tube radiator. We understand you have a bottom tank E.81084, which can be used on the small tube radiator. The second large tube radiator should have a standard bottom tank E.81372. This will mean that the large tube radiator is fitted first to the bumper chassis.
