I think this group is from 1985 but I haven't confirmed the exact dates, so any confirmation would be appreciated. As these haven't been dated, the file name is only temporary, so my normal labelling rules can't apply.
This could even be as late as 1989 given the Lyle & Scott branding. Rob Walters Lotus 23. I presume this is a genuine Lotus 23? Note the earth banking as track construction is one of the guides for dating.
Probably Tony Roberts, on the no longer used club track extension.
I doubt anyone needs this captioning.
...or this
Cooper Bristol of course and again, no fixed date.
