There used to be a seller on ebay who sold reproduction flutter wings. I believe her name was Nora and she might have been from Germany. Also, we had a member, GypsyWildflower who also made and sold amazing repros.
I know that MyLittleCustoms.com used to sell GypsyWildflower's wings. Maybe you could contact Piper (that's her Arena name but I can't remember her real one - sorry
) and ask if she knows how to get a hold of a pair.
Also, there are a few custom tutorials if you are just looking for some pretty wings and not necessarily reproductions of the originals. Pinkkittywinks also sells some gorgeous butterfly style wings for flutters.
Good luck!
