SDC11662.JPG Here's another picture of the Williams - and the legendary Henry Body (in the grey coat - it looks like Steve included the coat and trousers in his pic!), who at 80+ was still competing in sprints on the Douglas, exhibit 461. Looks like the ACU might have finally managed to ban Henry t...

Yep - spotted at Shepton today! (Damn cheek parking a ratty BM next to a pair of fine Ariels.....)
