There was a combined cutlery exercise with Robert Welch, in which a single range took on dual names, Campden and Spring, both made by Walker & Hall, the former sold by the Midland firm Old Hall and the latter by W&H. They were commercially successful, but such arrangements inevitably demand compromise. From then on the two designers worked in friendly rivalry. There was a solid fuel convector heater with superbly simple and graceful lines for Grahamston Ironfounders that won an early Design Centre award, as did his 'Symbol' cutlery of the same period. Seating for public spaces, municipal waste bins and bus shelters, vied with domestic ware in a burst of creativity. Prestige commissions and awards followed predictably; silver pieces for the Worshipful Companies, churches and universities, industrial commissions, an endless succession of design awards, OBE, Royal Designer for Industry, etc. And there was the Mellor shop in Sloane Square, where at long last the best of British professional kitchen and table ware could find appropriate display. Other shops followed. In 1990 a new studio workshop, the Round Building at Hathersage in Peak National Park, Derbyshire, designed by his architect friend Sir Michael Hopkins, won the RIBA national award and the BBC design prize for the year. Mellor himself was by then established as one of the finest silversmiths and metal craftsmen of the century. As for the rest, the work as ever best exemplifies the man.
