As it happens (oh dear,that sounds like Jimmy Savile), anyway, as it is,aog, our museums have plenty of stuff which could be sold off, to the benefit of the nation and without causing any loss to our perceived heritage. You can gauge that by seeing how many identical, or identical in style, pieces of porcelain there are in the Fitzwilliam and other major museums, or how many bits of ancient Egyptian material our museums hold, much of it repetitive, or even that one of our museums has all Turner's works, left on his death, and which are never on display and never have been, being of no exceptional interest.
Only problem is, or may be, that much of it has been given on condition that it won't be sold, or the museum itself is prevented, by its own charter or the statute establishing it, from disposing of the property.
Still don't see that one Hurricane, built in Canada and a late model, is particularly worth keeping here.
