The windmill was listed in 1951. It was probably the last large windmill to be built in Surrey. In 1952 the mill and land were acquired by the Croydon Corporation. The mill was threatened with demolition when the new John Ruskin School was built but it was protected by its listed status and strong public interest. An inspection of the structure found that it was in generally good condition, but recommended that the first floor doorway be unblocked to allow better circulation of air to prevent rot. During excavations for the foundations of the new school, two trade tokens were found, relating to the smock mill at Appledore, Kent.
