It was many years ago that Duncan sat in Heigham St and created Laslett.com/catalogue. At the time we were experimenting using frames with left hand side menus and automated email forms. Much of Duncans work is still in existance, although the email functions have now been upgraded by Joe and uses PHP.
Catalogues currently live in www.laslett.info/catalogue
One day the catalogue section will get an overhaul and maybe move back into laslett.com - in the meantime you still get a choice of catalogues that will be sent to your home by the company concerned.
