File (GUN) 2R Rm.{William Robotham - Chief Engineer}S/H.24.6.40. please contact Marriott and tell him that we want to put a firm order for 50 barrels, with Burton of the English Steel Corporation. Will you get an up-to-date drawing of the barrel and let Marriott have it. It was agreed at a conference this morning that fiftyfive tons ultimate would give a sufficient margin of safety for the barrel. It was also agreed that Rolls Royce have no objection to Vibrac unless English Steel have some objection.
