Please Help Fractions Collectors

Tried to run a search but it's been disabled. Wonder if someone has made a list of collectors for fractions and if so could you please pass on the link to me.

Have a couple of items like two warden's horns and wonder were I can take them. thanks

Look under the Canthan collectors, or type your item in the search box on the left to see a page specific to the item.

appreciate your reply, things are moving slowly at Guildwars.com,
