Well, there is no doubting that the plate is a 16464X number!! Which leads us to .... what? The 16464X block is part of an series of ARNs not listed in the BBB, but crossed out with the words 'engineers' scribbled across the page. From other sources, it contains mostly stuff like Paterson water purifiers, refrigerator trailers, street sweepers, rock crushers, rock drills, etc etc
Diana, you have opened up a whole new can of worms with this one: well done! I love a good mystery, but I think I might have at least part of the answer to this one already. I have record of only one truck listed among the 164XXX listing that went to SVN:
164643:Truck, 5 ton GS cargo w/winch, F1, 1967, engine 628302159; chassis 17689. RTA in Sept 1971. From your image, it looks like it was actually a bitumen truck, but maybe the bitumen sprayer were discarded in SVN, and a tray fitted for the journey home? Would seem reasonable when you consider one of the others was too bad to get clean enough to RTA.
Looks like M&D figures need to reduce GS F1 by 1, and increase Bitumen Sprayer by 1!
Well spotted Diana.
