| To Hl. 1124 Rm{William Robotham - Chief Engineer}/Mths.{Reg Matthews}19/JH.4.5.37. This is to confirm our conversation of the other day in which we asked you to let us have an accurate analysis of two cylinders, one as produced by Midland Cylinder Co., and one as produced by our own foundry at the time we were getting porosity. We should also like micro-photographs of the strcture of both materials and also Brinell, in fact a complete report covering every detail likely to have bearing on cylinder wear.
