| R.L.D. N/W. Rm{William Robotham - Chief Engineer}/Std. STD Br/G1/M.{Mr Moon / Mr Moore} 14.4.37. re, Tech. - Radiator Matrices. We received a P.III to-day, with a complaint of overheating in traffic. We have examined the Matrix, and find this to be stamped Mk.{R. E. B. Meade-King} VI. We compared the flow of this with one of the Matrices just received from RHC{R. H. Coverley - Production Engineer}, and it is identical. The three Matrices we have in stock are not actually stamped Mk.{R. E. B. Meade-King} VI, although we presume of course that they are. Will you please let us know by return if there are distinguishing marks to differentiate the Mk.{R. E. B. Meade-King} V and Mk.{R. E. B. Meade-King} VI Matrices, other than the individual Serial Nos. and the Piece Nos. Br/GG | ||
