| File Wraith Radiator To Rm{William Robotham - Chief Engineer}/Std. from G/Rb.{R. Bowen} 1260 P. G/Rb.{R. Bowen}6/K/73/W.5238. Wrote Rm{William Robotham - Chief Engineer}/Std. Wraith Chassis - Sec.5250 Filler Cap Scheme SCD.422. Rm{William Robotham - Chief Engineer}/Std.5/MH.{M. Huckerby}2.2.38. We have considered the cost of the alternative thread arrangements of the Filler Tube and Cap, i.e.:- (a) Filler Tube casting counterbored and with a spun brass insert sweated in position. (b) Filler tube casting with a machined thread in place of a brass insert. On comparing the cost of the two schemes, we find scheme (a) cheaper in factory cost by 4d. G/Rb.{R. Bowen} ewk. | ||
