Can't explain how they got there in either case, but not by GMH unless it was an error at the assembly plant (eg they drilled the holes accidentally so put badges in). Dealers did funny things, Taily's HJ Sandman ute had a whole front clip change with a HJ Kingswood in the same colour at the dealership.

GMH paperwork of the day common to both sedan/wagon and ute/van/tonner like options or colour/trim charts still use Belmont in the title but in order forms or other such literature specific only for commercials there is no mention of Belmont. The HJ Features manual part A was first published in 11/73 and there is no mention of Belmont in the full page descriptions of each type of vehicle so even that far back they were never to be a Belmont.
