Is that gadget behind Action Man an electric space heater? It would be interesting to remove the probably dangerous heating coils and install lamp sockets instead. That odd retro-futuristic case would make an interesting light fixture.
Normally I am not a fan of "destroying" vintage items for decorative purposes, but modern electric heaters are much more efficient (and less dangerous), and this particular item is probably of more value for its aesthetics than its functionality today. Also, it would likely be possible to remove the entire interior without damaging it, if you did
want to restore the heating element.
Too many questions about some old gadget that you only saw in passing on a television program, isn't it.
