Hi Warren,
Both Humber and Commer were part of the Rootes Group. It was a marketing decision to call them Humbers in the UK, based on Humber being a known name for military vehicles (eg.Humber Amoured Car). I expect it was a similar decision for Australia?? Maybe the Commer brand was recognised as more "Truck", with Humber more "Car".
A full restoration would be a serious undertaking, they are heavy and awkward to work on and takes a bit to get your head around the design. But this goes for all the British vehicles of that era, you should see the ones that did'nt go into production!
Mind you, there are advantages, you can talk while driving, and the ride is surprisingly good.
As for the much maligned Champ; buying one turned out to be the best thing I ever did. You just can't tell, can you.
Rich.
