| ET/HC. [struck through] c. Rm. {William Robotham - Chief Engineer} c. P.P.D. [struck through] 628 DA. {Bernard Day - Chassis Design} 4/G.17.5.38. WRAITH III - GEARBOX. Please receive herewith FD. {Frank Dodd - Bodies} 174 shewing Overdrive ratios in the standard Wraith III gearbox. This was prepared as a result of a representation from Sales that Wraith would probably require an overdrive to conform with P.III and B.III. This is no longer considered to be likely, so this drawing is sent you for filing purposes only. DA. {Bernard Day - Chassis Design} | ||
