My favorite British pottery site:
http://www.thepotteries.org/allpotters/1099.htmthis should take you to the Wood page, and follow links, and scroll for marks -
and this site, best on web for replacement values, may help you with your dinnerware (if you don't know pattern name, click on left side blue banner and it opens up all the patterns - happy scrollin')
for chamber pots, pitchers, etc, do a google or MSN search as follows -- enoch wood chamber pot -- or whatever the maker, or article is -
another easy to access site is:
www.kaleden.com select porcelain & pottery, and fine tune by the item - pitcher and bowl set, and if that returns too many hits, then further fine tune as pitcher and bowl set enoch wood & son -
Post back if you want to with pics of object & backstamp and we can help you search - best wishes, KB (sounds like you've got a nice collection)
