From Jim Irvine's archive, he thinks from 1983: L to R ? (might be Malcolm White), Nigel Stilman (I believe went on to fame as designer etc for Games Workshop?) Nigel Brownjohn, Ian, Andy ? and Simon Bacon. I think this may have been "clean up before a photograph" time. If you look closely, the line of diggers are all on their knees just outside the cutting, working away at the very edge of the cutting.
