| From Exp. Dept. Copies for: Mr Johnson Mr Royce Mr Bailey Mr Hadin AW/T&H19/L2413 April 2nd. 1913. Report on Experiment No.155/B Side Lever Mudguard (4-speed) This guard consists on a piece of sheet aluminium bent to a simple shape and is bolted to the pendulum gear lever in which the change gear lever works. The object is to protect the sliding blocks at the lower end of the change gear lever from driving mud. This it does quite effectually. The piece is simple, cheap and light. S. S. 20M-1000/10/12 (T.
