Judging from the reg. plate it’s an early one, Barry. A little later, if it had been an oiler, it would have had a Perkins badge on and later still the “Diesel” script on the offside which meant that one of those new-fangled Bedfords was installed. Unfortunately, my old memory cell doesn’t let me remember which years the diesels were first fitted but I’m guessing it must have been around '52 or '53.
