LARKSPUR. "Larkspur" was the code name for a broad range of British Army radio equipment fielded by a number of Commonwealth countries in the 1950's. It interconnected via a system of different harness and 'J'-boxes, depending on the requirements. Consequently details on the harnesses are helpful in setting up a realistic Larkspur station. The file titled "Harness" is "Notes for Royal Australian Armoured Corps Radio Instructors - RAAC Control Harnesses and their Operating Procedures." The file titled "Installation" is "User Handbook on Installation of Wireless Stations in B Vehicles". B vehicles are Long Wheel Base Land Rovers. "B 48" is "User handbook for Wireless Set B.48". The B.48 was a low power FM 'B Set' with a frequency range of 26-38 Mhz. The mechanically similar B.47 covered the range 38-56 Mhz.
