I don't have as much info on the overseas Jeeps as I do the US ones but this is what I gather from what I do have:

As for the Brazilian models. I suggest listing them Willys-Overland Brazil (or WOB as the make is actually Willys-Overland do Brazil) WOB was only around from 1954 until it was sold to Ford in 1967. (after that Jeeps produced there were sold as Ford Jeeps)

and while I am at it IKA was sold as IKA (make) from 1955 until it was sold to Renault in 1967 changing it to IKA-Renault (make)
