| To Hs.{Lord Ernest Hives - Chair} from DA.{Bernard Day - Chassis Design} X8520 DAL/M5.9.25. HYDRAULIC SHOCK DAMPERS. X. 8520 X.4046 AS you know we are going into the question of a suitable hydraulic damper as far as we can. Mr. Royce instructed us to get any samples that we know of that are likely to be any good; and accordingly, if you could send us down a specimen of, for instance, the 'Derihon', it would be of use for discussing with him. We do not know of many hydraulic shock dampers. We believe there is one called the 'Wilson', of a piston type, but do not know whether it is alive still. Any specimens you are able to send down we shall be glad of. DA.{Bernard Day - Chassis Design} | ||
