Found 3B courtesy of Chesham's website:
Beaconsfield 2, Chalfont St Peter, Chenies & Latimer, Chesham 2, Kew 2, Marlow Park, OMT, Reading 2, Teddington Town and Wooburn Narkovians.
By process of elimiation I think make 3A, not in alphabetical order:
T&T, Hurst, Wargrave, Eversley 2, Wokingham 2, Purley, Henley 3, Ascot, Falkland 2, Newbury.
Pretty sure Eversley have come up as best 3rd place finisher. Farnham Royal seem to have gone into 4A. I'm guessing that their 2s have become their 1s, 3s the 2s etc?
If I'm right then Ascot have a relegation reprieve, reasonable side or one you expect to struggle again? I'd imagine Wokingham and Falkland will be useful, no idea about Newbury. Eversley, if they've come up, are a useful side and they've found a couple of good batsmen to back up their good bowling unit. Nice local league which is always nice
