Old Soar Manor in Kent was acquired by the National Trust (1947) and subsequently placed in State Guardianship (1948). Margaret Wood prepared the paper guidebook in 1950 and it continued in print until the 1970s. The guide has a short history and a longer description. A floor plan of the house in c. 1290 is included.
