"As i said my own disenchaantment with the NT has little to do with content just the way the NT corporate image and branding is sucking all the interest and originality out of so many of their properties."
I really don't understand your comment above. Are you suggesting that when the NT repaint a room that they use their corporate colours or using the wrong period soft furnishings. From what I remember tea rooms and the shops were in outbuildings and not in the main house.
I remember visiting Fellbrigg Hall in Norfolk which was given to the Trust after the only son and heir was killed during WW2. What I particularly liked about the house was the continuity through decades with different generations adding to the contents, such as the Chinese furniture, including some Chinese Chippendale, and early 20thC water colours. Standen and Monks House were also favourites.
You are very lucky in England to have such a good collection of houses, usually with original furnishings and art works, that you can visit.
I live in the Dordogne, land of 1000 chateaux,many of which are open to the public and most of those do not have much in the way of contents so they are rather soulless places.
