| X4535 W.H. REYNOLDS & CO. BIRMINGHAM. Oct. 22nd. 1927. Our ref. RJD/JHE797. Your ref. ROY {Sir Henry Royce} 26/MG21.10.27. Messrs. Rolls-Royce Ltd., Derby. Gentlemen, In reply to yours we shall be pleased to mount you samples of P.O. alloy but we are afraid they will not give you your desired results. We shall also be pleased to mount you some samples with our D.G.S. alloy from which you will get better results, but as Iridio-platinum is now a reasonable price, of course these we shall recommend. With compliments, W.H. Reynolds & CO. P S. We are at present supplying you with P.O. metal with 10% fine gold and 90% fine silver to your specification D.50511. | ||
