Richards used to be a big mass market manufacturer of pocket knives. In the days when you could buy a souvenir penknife of just about any place you went most of the time it'd be a Richards. I remember my brother having one from Jodrell Bank. Wish he still had it
I've seen that set on my carboot hunts a few times though never in that good a condition. Total bargain price you got it for Mat, well done
