Recipe Request: Fuller's London Porter Clone

Does anyone have a decent clone recipe for Fuller's London Porter? I have tried a couple of different recipes, and can't quite nail it down. Any help with a recipe (can be extract, partial mash, or all grain) would really be appreciated.

Also, does anyone have the clone recipe published in the May-Jun 06 issue of Brew Your Own magazine? (I think I might have to try and order that back-issue -- there are a whack of porter recipes in there.)

Thanks!
