Hi Richard,
Both of our Fs (hers and his) happen to have had their last tax disk in the glovebox when we bought the cars and both cars do display their final tax disk. Judy's car (pictured) also still wears its UK registration plates placed under its current Ontario plates.
We most certainly do appreciate our Fs, and take great pride in owning a couple of these great little cars.
Here's a picture of the car on the show field in Louisville, US, in the concours class at MG2016. I put the flags on the doors after judging was finished. Of course the union jack was used by Canada until 1965.
