The supplier of standard diving equipment to the Spanish Navy, was Joaquin Carbonell Gimeno, S.A. of Barcelona. It is believed that he manufactured diving helmets for the navy since the early nineteen forties. Somewhere in the nineteen fifties he became importer and dealer for La Spirotechnique. Around 1980 the 12 bolt Carbonell Gimeno helmets were advertised in the french magazine ‘L’avonture Sous-Marine’. These helmets were not carrying a Carbonell Gimeno badge, but instead they had a badge marked ‘La Spirotechnique, Barcelona’ on them. Please read the ‘La Spirotechnique Barcelona’ Chapter to learn more about these Spirotechnique Carbonell helmets.
