ÔSIGNAL and WIRELESS STORESÕ, Notes On Equipment, Volume IV, was a British World War 2 publication issued by the Training Establishment, Royal Army Ordnance Corps (RAOC), ÔFÕ Branch, located at Donnington in the U.K.
Originally intended as a training guide for RAOC personnel, ÔNotes on Equipment, Volume IVÕ gave an interesting and fairly complete view of standard Army Signal and Wireless equipment issued in the early war period. Apart from the (obvious) care and handling of Signal Stores, the publication included essential basic theory of electricity, magnetism and all forms of electric power employed in the Army, in addition to wireless theory including valve principles. It also covered the essentials of a complete wireless station and explained the ÔXÕ and ÔYÕ classes of stores.
Although not a strict stores reference book, it covered W, Y and Z stores vocabulary numbers in the complete station lists. See also www.wftw.nl
