The local studies library and collection would be a good place to look, but there is another source in Croydon. The Croydon Natural History and Scientific Society, founded in the nineteenth century, is one that has local historians amongst its membership. They have a museum at 95a Brighton Road, South Croydon, CR2 6AD and their web-site can be seen at http://www.greig51.freeserve.co.uk/cnhss/ John
