Footnotes:
The most commonly used British SOE spy radio used in World War II was the B2, designed in 1942 by Captain John Brown at SOE station IX, and manufactured by the Radio Communications Department at Stonebridge Park. The set was standard issue to both agents and Resistance groups in occupied territories. This example is in its period brown/red cardboard suitcase with two locks, with most of the spares required present. Unfortunately the B2 was heavy and large, and would often sustain damage when parachuted into enemy territory, so they started to be sent in broken down into units in 2 water tight metal containers which could survive a drop. The second problem for this radio was its weight, some 34 lbs, and its size, which made taking it on public transport around occupied Europe hazardous.
