There were only about 12 made. One for each member of the team and one presented to the Royal Scottish Automobile Club for its clubroom collection. One was seen at Glamis Autojumble about 30 years ago, but the member who saw it did not realise quite its rarity and had I known, it would have been bought back then.
One may eventually come up for sale, but if you do find one please let us know where it came from, or as much as you can find out.
