During the war years, the West End venue was commandeered as a factory for the production of barrage balloons.
Manned by the Women's Auxiliary Air Force (WAAF), the hall, with its cavernous interior, became the chief factory in the UK for making barrage balloons, convoy balloons and inflatable dinghies.
Over 850 people worked in the plant.
The huge balloons, filled with hydrogen gas, were tethered to the ground with steel cables and were floated over potential targets to deter dive bombers.
This crew, in their blue overalls and wellies, certainly took pride in their work and were happy to pose with one of their 'blimps'.
