SHOCK DAMPER BELLOWS - WRAITH These Bellows which save 10/7d per chassis, have been tested on one of our experimental cars. Preliminary tests, however, show that the riding qualities of the car are inferior. It is, therefore, impossible to standardize these bellows immediately for B. Series. Tests will be continued and it is hoped the position will be reversed after B. Series. ROY{Sir Henry Royce}/Les.{Ivan A. Leslie} | ||
