I'm going to give you the point for that. I have found various pictures of the car at British shows, this one was the Hot Rod and Custom Show at Beaulieu in 2011, and it is always captioned as a 1946 Ford Woody Pro Street (I know little about the Custom scene, and I assume that this is a class of drag racing).
I agree with you about the front end being Willys, and I guess that like many custom cars, this one has been built from an assortment of parts, with the base chassis/motor being '46 Ford. I really like the unusual woodwork design, and left the registration details on the photo to see if the Rookies would take the bait.
Front end.......
