I've just purchased a Russian Flora jacket for £20 from eBay. Bit darker than most Flora I've seen, but is new and appears legit, or a very good copy. Doesn't have any manufacturer label, but looks like it has official russian military stamping.
@ Ian Gere - I would appear to fit a 52-3 if the jacket is correct, so you was spot on! Not sure how trousers work though. I'd be a 30 leg and 34"-36" waist as my weight is variable.
