Thanks Alex, yes Trak Grips look nice although these seem to be a little skinny.
I've looked up what history I have on it. In 1984 it must have still been owned by a Mr. Sidney Bolton. He reportedly bought the truck off a farmer in the 1960s, who in turn had bought it at a Ruddington auction in 1949. Mr Bolton had tidied it up to use and sold the truck in 1989 to Alan Levell who first fully restored it - see pic below and read more here:
