Dear Sirs, When we were discussing the characteristics of your "No.6" material and Hyco on the 'phone yesterday you said that one point of difference was that the latter contained some litharge in the mixture. We did not quite appreciate what are the merits or otherwise of this inclusion, and should be obliged if you would give us this information. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
