Thanks ever so much. No I'm not that Infoman,I'll change the name (if I can) now that I know there's another one out there !
With the 71/72 clubs,I'd worked out that there had been 12 games played by each club,which would mean 7 clubs in that section. I had Bromley,Grays and Maidstone.You kindly added Gravesend,Erith & Belvedere and Sheppey Utd. Does that still leave one more ?
