Consol Portable Shelters

Fair point there Simon, but if bombs were dropping on the factory then all is lost but if incendiaries are falling onto the factory then all is not lost and early warning of such devices is vital. That is all the consol shelter could do, protect the fire watcher. Its the same with 'protected' airfield buildings, the floors and roofs were nominally fire proof (Smith floors) for example in sergeants messes etc, the protection is always for fire never bombs. But yes always trust the RE, never the advertisment.

But yes always trust the RE, never the advertisment. And the information boards at certain museums!
