| H.R. 233 A (150 M) (V.V. 522. 10.2.13) G.{Mr Griffiths - Chief Accountant / Mr Gnapp} 0345 x2) J.{Mr Johnson W.M.} for R.{Sir Henry Royce} 2.3.14. Dal/G2314. In reply to your note RD/P24214, the parts of front axles broken on the bumping test have all been improved, that is to say, the cross steering levers have had the section improved for torsion, and the longitudinal one the same. The longitudinal steering tube has been improved in the matter of the taper already and is being further improved at the present time. The buffer springs are being increased in diameter and length, and the axle itself has been strengthened at the portion where it broke. I am obtaining permission for the improved buffer springs immediately. I will send you drawing of the axle in the course of a day or two. Da.{Bernard Day - Chassis Design} WS | ||
