Sorry for the long delay in replying folks, but due to an on-going problem with my old PC (now gone to laptop heaven for ever) I could not access this puzzle. Anyway, problem now resolved, so time for points to be awarded, as follows;
M630 (good name; I assume you like Matras?) gets one point for spotting this to be Ken Hill's 'Flying Banana', and one poin also to Sixtee5cuda for correctly identifying the locastion as Watkins Glen, late 1948. Well done both.
