A long serving companion at the work bench

Circa 1978. I lived for my manual training classes of metal work, wood work, tech drawing and running at High School. My manual training teacher had been involved with bike racing so we got on well as I was dreaming of being another Eddy. For some forgotten reason I needed to use a divider for a project at home. My teacher said, “take these” I will bring them back on Monday. He said, “keep them, you will make good use of them” Nearly 40 years later I reflect on the story of these Moore and Wright dividers that have lived on the back of my bench. They have been used on every Llewellyn frame set I have made. Did I make good use of them?
