Looking through a
a friend's pictures I saw a board about an XK120 which was the first non-US car to win a NASGAR race. It was at Linden Airfield in 1954, driven by Al Keller.
Rummaging around the 'net for more information, I found that there was a Morgan in the race too. Car 69 was driven by Jack Farnell, in his only NASCAR start, who finished 41st having been 7th on the grid.
