| SECRET. 804 Sg.{Arthur F. Sidgreaves - MD} from Rm.{William Robotham - Chief Engineer} Rm{William Robotham - Chief Engineer}2/R.2.6.38. 1-B-50 BODY. Further to our conversation on the subject of 1-B-50 body the other day, attached is a copy of a report which Ev.{Ivan Evernden - coachwork} got out at my request which illustrates pictorially the difference between the bottom sides of the all-steel bodies that we have been running up to date, and the new type of construction used on B.50. Since the type of all-steel construction developed by Ward is more or less unique in that it is made with low tool cost and it has proved to be very reliable, we think that a cost analysis should have been got out showing what would be saved by departing from proved practice before the modification was built into an Experimental car. Maybe this has been done, but figures were not produced when we queried the alteration. Rm.{William Robotham - Chief Engineer} | ||
