| UNDERSHIELD 10-EX. Undershield as indicated on N.sch. 2307 only carried rather further back for preference with a slight downwards dip at the rear end to throw air current clear of the rear axle. Also undershield should definitely throw air clear of rear brake shafts when car in standard position at rest. Normal drag caused by brake shafts appreciable. | ||
