Unfortunately there are none out there.The last one I sold went for $400.They will sell for more than the radios.The Greek government has surplused out about 65 sets all with no battery boxes so I have a list of guys looking.I have been in the restoration bussiness for nearly 40 years and I know every where in the world to look and there are none.The reason they have no battery boxes is because the Greeks like the Italians used the BC 1000 battery boxes with their post WWII British WS31 radio so that the US harness and belt could be used with WS31.
