For an upcoming stage role, I need to assemble a reasonable copy of the current uniform of a London (U.K.) "Superintendant"

I've looked around online, and not found much in the way of decent, detailed pictures... other than a few short of Rowan Atkenson in "Thin Blue Line", but even those don't have enough detail

Any UKers know a cop they could click a few pics of and send to me?
