I run the Richard Wheatley Museum website (
www.richardwheatleymuseum.org) and am currently trying to draw up a list of all the sales codes used between 1912 (the earliest catalogue we have) and 2008. Does anyone have a sales catalogue, product list or anything else that I can use to fill in some of the gaps ( a photocopy will do). The list is available at the moment as a free down load from the website but there are still gaps to be filled in and changes to be recorded.
Any help will be gratefully received
