And Franky, don’t forget that of the 16,000 Big J’s produced probably 60 - 65% were rigids of various configurations and medium weight tractor units. AEC were supplying Guy with 1,000 plus AV505 engines per annum for several years, Leyland supplied the O.400 engine as well. I think that the research that Valkyrie did with the Gardner engine records is probably the most accurate that there is. Personally I do believe that a factory built Gardner 8LXB powered Guy Big J did exist but an original, authenticated photograph would be nice.
