My father was at Richards too, I remember it as George Richards, and also as Richards & Tilghmans. He worked there all through my childhood in the late forties and the fifties, right through into the sixties. He was made redundant in 1967, and following an accident at his next job, died in 1969.
One of my most vivid memories is of him coming to meet me from school and giving me a ride on his bicycle crossbar on his way home for dinner. If you know Altrincham now, you will know that there is a road named George Richards Way which runs parallel to Atlantic Street.
