There was some confusion as to the lettering for the various types of brushes submitted by the Morgan Crucible Co. Their sample, which was in accordance with our requirements was marked C.M. but the brushes which gave satisfaction, although apparently the same material but were bought in pre-war days, were marked C.M.1. We have already supplied the Morgan Crucible Company with a sample brush to avoid any chance of their supplying us with a wrong grade of material. Will you kindly write to the Morgan Crucible Company and obtain from them the exact lettering of the material of the sample brush which we submitted, and which they agreed made our order quite clear in their letter of March 18.
