I seem to remember Blundells also operated their own trucks but have been unable to confirm this with my Uncle.
What I do remember is a very bad accident at Slipper Bridge opposite my house when a Blundell Permaglaze lorry hit a van head on killing both drivers. I was about 6 or 7 years old and it was the first dead body I had ever seen. I saw a lot more accidents along that stretch of road too. After the paint lorry accident, the paint had soaked into the grass and for many months I went home with paint up my legs.
