| HK{Col. T. Harker - Sales} Hs.{Lord Ernest Hives - Chair} ✓3854 By Unrequest needed BY2-P30.1.24. 40/50 CHASSIS. FRONT SPRINGS. I have just received a note from Messrs. Woodhead in which they inform me that they have despatched four main plates with solid eyes which have been heat-treated to a lower brinell figure, and in addition have been made from Silico Manganese steel. Messrs. Woodheads have got mixed up on two separate issues. I wish to have solid eye main plates made from their standard material in the lower brinell, and secondly, I intended to try Silico Manganese as used by Messrs. Woodheads and Messrs. Firths. In any case, these will represent useful information, and I would therefore like you to put them on the bumper as soon as they become available. I have arranged for Mr Marriott to keep in touch with the O.O. and see that the plates in question are handed over to you as soon as they are received. BY.{R.W. Bailey - Chief Engineer} Ry | ||
