| To EH. from E.{Mr Elliott - Chief Engineer} X. 3205. RE TUBES FOR CALCOTT CAR With reference to the two tubes you sent us recently we find that the valves of these tubes are smaller in diameter than those usually fitted to this car. We have put a micrometer on them and they measure .485" as against a diameter of .590" for the old valves. We propose returning these tubes to you as we prefer to have the correct diameter of stem, but will do nothing until we hear from you.(as per Mr.Royce's instructions).
