I've got a 130mm 3TTT road stem (i.e. 26.0mm clamp) in shiny silver knocking about somewhere, +/- 17 degrees maybe (more than the usual 8 or 10), and can be flipped, pm if interested
London, the magazines are somewhere at my folks' place in Kent, but I could get hold of them easily enough.
Would presumably cost an arm and a leg to post though!
