| RR 755 REVISED (10H) (DE 444 6-10-26) BM. +8430. COMPLETED 23.12.26 STANDARDISATION of CHASSIS PARTS. Date 26.11.26 Description of Parts. WEAKER SPRINGS IN SIDE STEERING TUBE. X No. 8450 8430 Drawing No. F.76108 Part List Origin. To reduce steering shocks. Experimental Test Report. 1500 lbs. side steering tube springs were run with the lightened axle in France 10,000 miles. It is therefore proposed to standardise these springs with this axle. Road Test Report. These springs effect a very pronounced reduction in road shocks and yet give a selective steering with the new axle.
