No i don't. There are already images and coins which show some kind of wings and there also also enough symbolic in Persian art that shows winged creatures. So there is obviously a connection with wings. What i did was explaining why there would be probably no helmet find which has them. It is the same with this for us strange looking crowns/turban like headgear. We haven't a surviving piece of it and we aren't even sure about the material they are based of but we are very sure that they existed.
