Worth noting that the old parish boundaries are shown well on the ooc 1:25k mapping. Of course we have major gaps in these maps currently but... all in good time. Except where boundaries have been moved to meet changes in landuse, especially where towns and cities have expanded, the current local authority boundaries often still follow historical parish boundary lines. Incidentally I have ooc 1:25k sheets for Maidstone and Chatham which I'll be uploading this week.
