There are a tiny handful of Series 2a here with 'Land Rover Rhodesia' data plates on the firewall, but they are rarer than hen's teeth. I'd love to have one!
I think in fact the running gear on the Pookie and Leopard came from VW Kombis (camper vans or mini-bus), not Beetles - not that there's a lot of difference. The Moon Buggy and Kudu were Landy-based - thanks to https://tanks-encyclopedia.com/category/rhodesian-apcs/ for the images!
