Yeah I needed swan feathers for my quarter pound arrows. They don't sell them, as they're usually backed up with orders for over 3 thousand feathers for various people. It was a result of a lot of chatting and meetings and eventually agreeing on a couple of display arrows in return.
Funny thing is, they let me sift through their buckets and pick 21 perfect primaries, and the week after I took a punt at a local lake and walked away with over 150 swan primaries so didn't need to make some arrows anyway! Still, nice to have some of my work on display I suppose.
