Here is a link to a website to play with. It has lots of information including old and up to date maps re North Lincolnshire (and everywhere else in the UK). http://www.visionofbritain.org.uk/unit_page.jsp;jsessionid=67E21C294D4BA44DB702BAC6E0792E9F?u_id=10189019&x=3309261.71585&y=3018764.37576 BTW, there are two Beltons in Lincolnshire - you need the one that is prefixed by the word North.
