Re: Bump Test.

Will you please fit the 40/50 bump chassis with the latest bijur scheme connected to the axles, also with a pair of rolled eye springs erected "dry" as we wish to test the lubrication of the rear end. We should like to use the springs off 24-EX. and run a pair of solid eye springs on this car.

Will you also fit a pair of case hardened inner levers to the rear shock dampers. These are being instructed by the D.O.
