| To PN.{Mr Northey} From Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} c. to Sg.{Arthur F. Sidgreaves - MD} Wor.{Arthur Wormald - General Works Manager} c. to By.{R.W. Bailey - Chief Engineer} 85410 Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}6/KT.11.6.31. LOW RATING SPRINGS 20/25 HP. X.7960. X.235. X.5410. We understood, during our last visit to London, the comments on the springing of G.L.R.59. were not wholly favourable. We anticipate that it may be found that the compromise we have effected is not ideal for conditions of London demonstration, and we would therefore recommend that you make a further test with the .055" diameter leak inserted in the high pressure valve of the front shock absorbers. The general effect of this modification is to soften the suspension and generally improve the riding in the back seats, though the controlability of the car may suffer somewhat at high speeds.
