And you could also try Avoncroft Museum of Buildings on 01527 831363 or 01527 831886 and although miles away, you could try:

Let me know if you find somewhere for it ...... I know there is another "living" museum up north called Beamish, but have not given the details as it's a long way from you but might be worth a try if all else fails.
