John, After peering into the rear windows of many cars at various car shows (and
getting some strange looks), I can confirm the ashtray is from the back of the
front bench seat on some fifties Fords. I am pretty certain that it’s the Mk1
Zephyr Zodiac. I’m at another show this weekend with my Morris Cowley, so will
be in the midst of the fifties saloons and will continue the research....
possibly with photographic proof! Steve 232PR Else.
