Yuletide beta -- ISO Brit Picker, pre-Thatcher England

[rthstewart]

I am in the throes of my Yuletide assignment and am finding I really need a Brit-picker, ideally with some feel for pre-Thatcher, 1970s England (with added Oxbridge references and slash subtext).  I know the fandom and the characters well (book and film) -- that's not the problem -- but I think the draft so far reads very American with lots of added "u"'s in words.  I just don't know the idiom, the slang, or the geography.  I'm looking for a gritty, British feel and all that seems to happen is reuse of the words "grimy," "soot," and "exiled to the Siberia of Brixton."    I'm at about 4,500 words and I think it will be up to 6K in the end. 

I looked at the Yuletide beta list and the ones offering for my fandom are all Americans. If you are interested/can help, please drop me a line or comment.  Thanks!
