Body weights O.K. 100 lbs. stronger rear springs fitted. Other complaints. ☒ 124-XJ. Sir Pomeroy Burton. This is a complaint of "dithers" and should be overcome by drilling H.P. valves in rear dampers and increasing damping to 80/100 lbs. 121-XJ. Barclay. Dithers and "bumpy" in rear seats. Drilled H.P. valves of rear dampers and increased damping. X 153-XJ. Grimstone. "Bouncing" at rear. Rear springs are on the weak side but we are trying the effect of increased rear damping. 83-WJ. Mrs. Manning. Dithers in rear seats. 2 passengers only. We are drilling H.P. valves of rear dampers and increasing damping. ☒ 47-WJ. H.{Arthur M. Hanbury - Head Complaints} Tevis.
