Martindale} Rm.{William Robotham - Chief Engineer}11/MH.{M. Huckerby}23.9.38. In order to allow production material to be ordered by March 1939, the frame will have to be completed by the end of November of this year so that dies may be put in hand. Experimental work should, therefore, be completed with this objective in view. Rm.{William Robotham - Chief Engineer} | ||
