Engineer}10/AP.13.7.37 PH.III. AND WRAITH HORN BUTTON. With reference to your E.2/HP.19.6.37, we are very anxious to receive your alternative scheme for the Ph.III. and Wraith horn button, so that it can be fitted to wraith when on Production. We have a very bad example of a rattling button on the grey Wraith, 25.G.V1. which has been the cause of bitter comment from Mx.{John H Maddocks - Chief Proving Officer} and Rm.{William Robotham - Chief Engineer} Rm{William Robotham - Chief Engineer}/FJH.{Fred J.
