| All Testers, from Rm.{William Robotham - Chief Engineer} c. Rm{William Robotham - Chief Engineer}/HH. Instructions to Shop Rm.{William Robotham - Chief Engineer}7/HL.25.3.41. 1373. DRAWINGS FOR PURELY EXPERIMENTAL PIECES. From time to time it is necessary to enlist the Drawing Office's assistance in preparing drawings for pieces for development work. We agree that Rm{William Robotham - Chief Engineer}/HH. can do this work, but such drawings should have an Rm.{William Robotham - Chief Engineer} number so that they never get confused with production drawings. Furthermore, requests for such work to be done must be accompanied by Rm{William Robotham - Chief Engineer}'s signature. Rm.{William Robotham - Chief Engineer} | ||
