If it isn't Austin 7 at least the wheels look as if they are - and why would anyone making something else use A7 wheels?
To make it look like an Austin 7 as much as possible I suppose!
I don't know a great deal about this car, just that it has its own name, after the person who built (and offered) it.
Whether he started off with an Austin 7 or just finished with one that looked like one I don't actually know...
