Eddie Heaton:
R & N Wright )Bob & Nick) were from Hoole, near Preston - when I first knew them in the mid 70s, they had 5 Mk.2 Atkis subbing for Pandoro.
Their business develop;ed over the years and they later moved into the old Horsley Smith yard in Bamber Bridge. I think it would have been the mid 90s when they finished.
