Not sure about Norrie Dan, I don’t remember him having that but he may well have run one? I do remember his six wheeler D Series Ford and that silly Volvo that gave him so much grief though! 
You dad will know for sure. That Dodge was the one that parked at Lea Mills I think but I can’t remember the chaps name! Mick (malmic) might be of help with both queries. I do remember that dumper, and didn’t they have an old Albion tipper?
Pete.
