Hawkins Transport.They own the barges as well.I think only parts of the cab are ally,a lot is still original steel.I remember years ago one of their 4x4s got bogged below the high tide.Couldnt get at it from the shore,so when it was submerged,they towed it with a trawler round to the jetty,and used the crane on the jetty to lift it from the water.Regards John.
