Rm{William Robotham - Chief Engineer}1/R.26.4.38. Metal Patterns for Wraith. With reference to RHC{R. H. Coverley - Production Engineer}/Vs{J. Vickers}1O/JT.22.4.38., this is to confirm that we anticipate the cylinder block to EW.1580 and cylinder head to EW.1296 are not likely to be altered, and, therefore, it is in order to produce metal patterns. The exhaust manifold to EW.1626, however, is not sufficiently stabilised to allow for expensive manufacturing equipment. Rm.{William Robotham - Chief Engineer} | ||
