| 664. Sg.{Arthur F. Sidgreaves - MD} from Rm.{William Robotham - Chief Engineer} c. Hs.{Lord Ernest Hives - Chair} c. By.{R.W. Bailey - Chief Engineer} Rml/R.22.12.38. With reference to Hdl/IB.2.12.38., which we discussed last time you were at Derby, and which I return herewith, the following is the position with regard to the modifications tabulated in this memo:- (1) The cylinder head changed. There are 39 cars which were despatched with the condemned type of cylinder head, and these will require changing. (2) Modified Speedometer Drive. The modification to the speedometer drive was necessary because, under traffic conditions it was found that oil did not get to this part. As you see, the modification has only a total cost of 8/3d, and 71 cars will require modifying. (3) Modification to the Instrument Board. This is necessary in order to prevent the bulbs burning out. Only 24 cars are so affected. (4) Replacement of the Distributor with hardened cams. 130 cars have left the Factory without the cams being inspected. We have ascertained that only a percentage of the cams are defective, but they will all have to be inspected. To these items, it is necessary to add the gearbox change, the propeller shaft change, and the modification necessary to ensure that the fan does not foul the radiator. There are also two inspections to be made which do not require any material (a) The ammeter terminal (b) See that all the wheel nuts are bedding satisfactorily on the wheel cones. We have never had any trouble with wheels in customers' hands, but consider it necessary to make the inspection since we have found experimentally that as manufactured by Dunlops, the clearances may be insufficient if all the limits go the wrong way.
