Further to my finding a 2012 photo of a Wasp on the side of the road in Malta (here: 
viewtopic.php?f=44&t=2276), in the same Googsploratoin, I found this!
http://durban.olx.co.za/isuzu-wasp-1962-iid-446702554Obviously the year is wrong.  The description is thus:
"This Pick-up is 50 years old , needs a face lift and looking for a good home, 1962 model .oldest known Isuzu pick-up in South Africa."

	 I could believe that!  It's not in bad nick, by the looks of things, and I bet it's as rare as rockinghorse there!
I wonder how it got there?  They sold Belletts there, but they seem completely forgotten now; we've got one user from South Africa with some GTs, but I haven't seen them on here for some time.

	 The price isn't bad, either.  R15,000 is $1646.13 as at today, so that's pretty awesome.
