| To Hm.{Capt. W. Hallam - Head Repairs} From Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} c. to C. X8774 Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}1/WJ.17.12.29. 10-EX CAR. As this car has been in Expl. use since 1925 and has been continuously modified since then it has rather a lot of Experimental pieces on it. We understand that C. considered that these pieces/have done 10,000 on this car and which we consider to be safe should be left on it. The parts which we think should be made standard are the frame, engine mounting, front shock absorbers, pistons, front axle, pivots, brake leverage. Attached is a specification of this car which we should like to have back for our records. The radiator on this car has recently been renewed.
