Yes Gizmo I have seen one before (but it wasn't here in Australia),I do know is they were sold as VC M as an export model.
So how that sticker ended up on a local mower I have no idea.
I noticed it before but as it was on the Victorian boarder I though it wasn't really worth the freight cost.It is only a VC Mustang Mark I with a different sticker.There was nothing else different about that model.That one didn't even have the right colour hub caps.It did seem to be in fairly good condition,but what worries me is generally when people sell their mowers and don't take pictures of the engine side you usually fine some damage (ie wear) on that side.
I hope that helps.
