Our daily report on 21.G.IV. of the 6th Sept.1935 explains why E could not find any trace of our modification. " GEARBOX. Ease of change good, lever free from rattle. " " Oil leak from bearing of new swinging arm, requires " " perfect seal as fitted to old one. Slack in rear drive " " coupling splines. " The sudden calling back of 21.G.IV. being the reason. Our memo of the 15th August explains why it was done. (Our ref.GWH{George W. Hancock - Head Chateauroux}/5/JAB.15.8.35.) " GEARBOX. Upon checking up level of oil, the box was found " " to be practically empty. There were three causes for this." " 1) Bijur pipe line clip & screw missing under Servo. 3/16 " hole left in box. " " 2) Bijur pipe line clip & screw missing under Swinging arm" 3/16 " hole left in box.
