| 1124 Cyl general file Mr. Rowbotham, for Doc. Smith, Re- 5 Cylinder Blocks E.B.2929 cast by the Midland Cylinder Co. The above Blocks are not up to the standard we require in the Bore and would be rejected for Dirty Patches and Open Metal in same. The joint of the Casting on the Water Jacket Side is a bad job. The Brinell Figure of these Castings is right on the bottom limit and we should require an improvement on this. J.{Mr Johnson W.M.} Clarke. | ||
