| R.R. 235A (100 T) (S.H. 159. 11-8-20) G.{Mr Griffiths - Chief Accountant / Mr Gnapp} 2800 TO HS.{Lord Ernest Hives - Chair} FROM DA.{Bernard Day - Chassis Design} DA{Bernard Day - Chassis Design}1/M5.9.25. HYDRAULIC SHOCK DAMPERS. 48520 Fourth As you know we are going into the question of a suitable hydraulic damper as far as we can. Mr. Royce instructs 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 discussion 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} | ||
