| X3695 Wd{Mr Wood/Mr Whitehead}/W2/E11218. 11th. February 1918. Messrs. Negretti & Zambra, 38, Holborn Viaduct, LONDON. E.C.1. Dear Sirs, With reference to your letter of the 31st. ult. we note that you are quite unable to supply a complete Compression and Explosion Pressure Indicator. Will you kindly confirm this and at the same time state if you are able to supply any parts of one of these instruments, say a complete disc valve. Failing this we should like to know particularly whether you could supply the Platinum Disc Valve as we believe we have one or two of these Valves by us which are complete with the exception of these discs. Yours faithfully, | ||
