XV. For fans of the great period television and film dramas Downton Abbey and Brideshead Revisited (among many others), one of the great pleasures is seeing the grand, sumptuous, imposing interiors of some of England's greatest homes used as stage sets in the drama.  This week's episode features Nick Dawes, master specialist and appraiser seen regularly on "Antiques Roadshow" who shares some insight into the decorative arts collections of some of these fictitious as well as some very real families.  Visit the Gilded Gentleman website for more information.
