| CONTINUATION No. 1. J.{Mr Johnson W.M.} W. ROBERTS LTD., ARMLEY, LEEDS, ENGLAND. Messrs. Rolls-Royce Limited. 13th March 1933. an expression of what might happen, but it occurs to us that should the assumption prove correct, the method of procedure should be to again raise the pitch by adding a baton to stiffen the panel, and so, by a combination of spray and the use of occasional batons achieve a distinct improvement. Yours faithfully, J.{Mr Johnson W.M.} W. ROBERTS LIMITED. | ||
