G'day All,
The Austin 'Champ' rims certainly look different on a Land Rover, I have a friend who has a full set on his 109Wksp Land Rover.
I would suspect that they were ??either trying them out?? so to speak, as it's certainly easier to change a flat tyre with a split "Combat" type rim as opposed to the normal Land Rover 272309 rim, just my thoughts on the subject, cheers Dennis
