Jenner} Ha/Rm.{William Robotham - Chief Engineer}16/KW.4.6.36. 20/25 HP. Radiator. Replying to E.2/HP.3.6.36. Owing to weather conditions Hancock so far has not been able to get a figure of merit for the standard radiator with the big bore engine. This of course is necessary to clear existing production. The car will be running again after the Whitsuntide holidays almost immediately, and as soon as the weather gets warm enough for radiator tests he will change over radiators.
