Tyrie's got a point, although I was interested in the use of the registered Ford word "Tudor". [Ford registered this spelling for use on their tu-dor models in the late 20's]
If this was a 4 door, a coupe, a ute or even a wagon, its value would be determined by the availability of other, better examples in the marketplace, but other, better 2 door 1200's are a bit hard to find in the Australian marketplace these days, so it's difficult to make a comparison.

What's it's true value? Beats me, but its rarity in Australia must account for something.
