[Margaret Pilkington]

I worked at the Carborundum in Clayton from 1969-1973.
Maybe he no longer worked there then.
There were also two sites in Clayton....the bottom factory(didn't make bottoms) was located at the bottom end of Lower Barnes St and made the huge rolls of abrasive material.
The top factory was what used to be The Spaanjards(not sure of that spelling...it was pronounced Spanyards) weaving mill on Oak St.
I can only remember one man called Frank...but his surname was Lupton.

I know this isn't a great deal of help but it might loosen someone's else's brain stones.
