Welch successfully sold one of his prototype designs to J. & J. Wiggin before he left college. A small family firm in Bloxwich, north of Birmingham, J. & J. Wiggin was the only British manufacturer of stainless steel tableware, marketing pieces under the brand "Old Hall". Welch did some work for the firm whilst still a student and in 1955, he was appointed as their consultant designer, an association which lasted until the firm closed in 1984. His geometrical ideal suited the material, and his passion for precision suited the factory.
