Compendium 1 "Spark to Larkspur"
(Wireless Sets 1910-1948)

Compendium 2 "Spark to Larkspur" (Special Sets, Receivers and Larkspur) is divided into five main sections and sub-divided into chapters by application, operational use, range or family of sets, and date of introduction.

Compendium 3 and 4 "Foreign Equipment Data Sheets" (Part 1 and Part 2) contains a facsimile reprint of a German World War 2 publication entitled 'Signal Equipment' ('Nachrichtengerät'), also known as D50/13. The publication is Volume 13 in the 'Foreign Equipment Data Sheets' ('Kennblätter fremden Geräts'), a series of German Army publications providing data on enemy equipment, principally from Belgium, England, France, North America, Russia and Switzerland.

Compendium 5 is a facsimile reprint of 'Signal Communication Equipment used by Enemy Nations', a British publication providing technical and operational data on captured enemy signal communication equipment originating from Germany, Italy and Japan. It was produced by the Signals Research and Development Establishment (SRDE) in co-operation with M.I. 8 and first issued as a secret document in January 1944.


Compendium 6 is a facsimile reprint of 'Notes On Equipment' a modern reprint of a 1944 document issues by the Training Establishment, Royal Army Ordnance Corps, F Branch, which was based at Donnington in Shropshire. Notes on Equipment, Volume IV, was titled Signal and Wireless Stores, and was intended to give Stores personnel a grounding in the line and radio equipment used by the wartime army.
