W/P. To Sr/VA. from Rm{William Robotham - Chief Engineer}/Std. c. Hd.{Mr Hayward/Mr Huddy} Rm{William Robotham - Chief Engineer}/Std.5/MH.{M. Huckerby}18.10.37. Referring to your Sr/VA.4/GM.24.9.37, your Sr/VA. 9/ET.4.10.37, and your Sr/VA.7/GM.15.10.37, by now you have presumably received our memo Rm{William Robotham - Chief Engineer}/Std.1/MH.{M. Huckerby}9.10.37, which we thought made the position clear. Referring specifically to the last paragraph of your Sr/VA.4/GM.24.9.37, the answer is that on the first series Ph.III, the majority of the cars were fitted with new Mk.V matrices, while a small percentage (of the order of 15%) were fitted with new Mk.VI matrices. This was due to the fact that although Mk.VI matrices were standardised from the start, Messrs. Marston Ltd. could not supply sufficient for our requirements at that date, the balance having to be made up by new Mk.V matrices. Naturally, at that time no reconditionned matrices were fitted since no trouble with silting up had been experienced then. It is possible to obtain from the works a record of which type matrix was fitted to any given car. We think that the Repair Dept. should obtain such a list and circulate it to depots, so that it can be known in advance whether customers matrix is Mk.V or Mk.VI Referring to Sr/VA.1/GM.15.10.37, the matrix of the car in question was No. A.34A, a Mk.V one. (If this number is quoted it is possible to tell from records what type of matrix it is.) This should of course, be returned direct to Messrs. John Marston Ltd., for reconditionning, this matrix being the original one fitted to this car. We hope that this clears up any confusion there may be. Rm{William Robotham - Chief Engineer}/Std. | ||
