Jim,
I am sorry I dragged this a little off course, but looking at the sort of chappie he is, he will be expecting a lot more than what the price is at the moment for the bit you are interested in, it will be nice to know what the eventual price is.
As for the quacks, I think the market he is aiming at isn't in the UK, but in the US, where they have a much shorter history than ours, and of course less artifacts, 'folk art' as they call it, is eagerly sought, and high prices are the norm, not the exception.
