It looks exactly the same except for the fact that in that article it says it came with a protruding boot which enclosed the spare wheel, here however there is no boot and the wheel is on the outside.
Can someone please explain why this is?

Austin Ten, 1932 on. Possibly the slightly later Lichfield model: http://en.wikipedia.org/wiki/Austin_10

I have been told it is an Austin but i have no idea what model/year it is, can someone help me out?
If someone has a link to an article about it would be even better.
