| Messrs. Rolls-Royce, Ltd., Date 23.10.31. Page 2 to different sized nuts being fitted at each end of the line. The pump line has a considerably smaller connector, the same at both ends, which precludes it being fitted in error to either of the other connections, as it will not go on. With this arrangement, by coupling the respective union nuts on to the [strikethrough]other[/strikethrough] unions at either end at random, without tracing the line, no mistake can be made in assembly. Assuring you at all times of our best attention, We remain, dear Sirs, Yours faithfully, H.M. HOBSON, Ltd., [Signature: F.P. Searight] Joint Managing Director. | ||
