Referring to your Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}2/MJ24.7.31, we are not quite clear as to whether the peculiar condition which Hancock refers to i.e. free movement of the lever under certain conditions, may apply to our standard shock absorbers, or only to those of the modified type which are fitted to 25-EX, and a pair of which are fitted to the rear of our trials car 129-GN. Also, whether the special high pressure ball-pin load up to 115 lbs. on this car is possible only with the special dampers or can be arranged with the standard damper. If it is likely that the standard shock absorbers may actually fail in action in the way described by Hancock because the seating of the replenishing ball-valve having become badly hammered, then should we not issue a Depot Sheet as a warning of this possibility.
