The Managing Director and founder of RCNZ, Mr W. Marks (born William Markov[1]), was single minded in concentrating the development of the company on the design and manufacture of radios and apart from some wartime production this was the case until his death in late 1946.
After clearing the space of some 50 years of foundry operations the ground floor initially contained one large and two small recording studios and a central control room at the rear of the building.
