I've seen pictures of jeeps in service with the Lucas/Butler sidelights, which would also be a mod to the standard as-delivered jeep. I'd imagine they were common in the workshops, and were easily on hand for a refurb or field modification.

The way vehicle stores were ordered, you may find that they are the general purpose version in the VAOS where the Canadian types would be vehicle specific, and thus harder to find without the right part number/parts list. Plus the scrap vehicle park would probably have had a bunch for recovery and reuse by enterprising squaddies. They were common to a lot of vehicles.

[s]That said, the hole in the wing in question doesn't look anywhere near big enough, so the normal canadian type look to be the right fitting unless you're modifying it.[/s]

Edit:Ah, just spotted the bit about re-welding, so it my have been bigger than it looks.
