Our friend from Belgium, Philippe Berger asked that he has a British Carbon Print from 1870s and he wants to know the list of used papers for that era.
This is extremelly wide vast array of research subject and there are very big catalogs for pointing the used paper from watermark.
If you have a very old print , hold it to the light and find the watermark and send it to British Museum , they will have an answer or directive for you.
My university library had enourmous catalogs from Holland. I think art and forgery is a multibillion dollars industry and I think Holland printed them to date the art pieces.
If you want to see a list of British , Foreign in British , British in Foreign Country Artists Suppliers dated 1650-1950 and their biography , follow below.
This is from National Portrait Gallery.

This biographical resource is devoted to British and foreign firms of artists’ suppliers and colourmen operating in Britain and British firms operating overseas. It focuses on manufacturing and wholesale suppliers and on those retailers mentioned by practising artists or who can readily be identified through advertising in nationally available newspapers and magazines or through the survival of marked products such as canvases, boards, colours and copper plates. For the earlier period before about 1810, artists, booksellers and stationers dealing in artists' materials are listed on a selective basis.
