The Larkspur Antenna Bases were widely used on vehicles from Britain, Australia, NATO, and other allied countries. Serving as the standard British radio system from the 1950s to the 1970s, it was installed on various Australian vehicles, including Ferrets, Saladins, Saracens, Centurions, and a range of wheeled soft-skin vehicles. Each kit includes four Larkspur Antenna Bases with antenna scaled at 6.9mm.
