RE 20 HP CHASSIS - SPRING DRIVE - SEC:5020.
DAMPING SPRINGS.

With reference to your conversation with Mr Bailey regarding a 25% reduction in the Damping Load as given by 10 springs E.52484, we find that springs E.14670 should be suitable.

These springs are used on "Eagle" and "Condor" Spring Drives, so will you please try out and report to Mr Bailey as soon as possible, using the continental bakelite Friction Discs E.53266.
