| W/S. To Cx.{Major Len W. Cox - Advertising Manager} from Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} 258. Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls}2/MH.{M. Huckerby}7.10.38. 'M' SERIES BENTLEY. Cx.{Major Len W. Cox - Advertising Manager}20/K.5.10.38. An increase in weight of just over ½ cwt. for 'M' series above 'L' series is correct. Most of this is due to the larger tyres, the increase being considered worth while. Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} | ||
