Uncommon manufacturer’s catalogue promoting a complete dental ‘unit’ for modern dental practitioners. The ‘Rathbone’ reclining dental chair together with attached spotlighting, small basins, and moveable apparatus trays, was ‘based on a thorough investigation of the needs of modern dentistry and a study of the possibilities and limitations of dental units generally. The layout is such that every piece of apparatus comes readily and naturally to hand. The position and movements of each component have been planned so that, when in use, the component can be brought to the most convenient position for the operator, and when not required, returned to a point where it will not impede him in any way’.
