| S/W. C9/C15.1.26, Re. 9-FK EXPERIMENTAL CAR. Hs{Lord Ernest Hives - Chair}6/LG21.12.25. BJ. agrees to your using 9-PK at Derby for special purposes, and that you should return to us for sale, car No.10-AU. This is conditional upon the car being passes by PN.{Mr Northey} or CWB. and we suggest that the next time either of these officials is at the Works you should ask him to try 9-PK. C. | ||
