Air Raid Shelters

 

In the run up to World War Two Ralph founded a company to market and build air raid shelters. The enterprise was variously known as the Bomb & Gas Proof Shelter Co.,  National Bomb & Gas Proof Shelters Ltd. and British Air-Raid Shelters Ltd. It is not known if any shelters of this design were actually sold or built.
