I've found this picture tag as Mini Scamp R Dudley.
"2003. In this year's Autumn Antics, 50 entrants took part in eight tests, run twice, on various loose surfaces. The Team award goes to the three drivers from the same club with the lowest total time, and five clubs had enough entries to be in contention for this. Individual Fastest Time of Day went to Roger Dudley, in his Mini Scamp."
Another picture:

And another:
"The 2005 Autumn Antics followed our usual format, with nine tests on various loose surfaces. The entrants, and award winners, included some familiar faces, including Roger Dudley, who was the overall winner for the third year, in his 1300 Mini based Scamp"
