For those that didn't spot it tucked in the middle of another thread, I have converted the BBC2 Wales programme 'To Wipe the Slate Clean', about Llechwedd and Oakeley, to DVD. If you would like a copy then just PM me your address and I'll get one in the post.
I don't want any money for it, but if you enjoy it perhaps a donation to your local cave resuce, or FoC would be appropriate.
