Keep up the good work. I just noticed the Accipiters chapter. I have never heard about them before and I cant seem to find anything about them.
I was only able to find a picture of them, this picture is from the Limited Edition 7th Edition Space Marines Codex.
I think I looked up most of those yesterday and found nothing about the colours and symbols.
Thanks for taking a look around for them. I know there is going to be a ton that have no official images to work from.
Also, I found more A's to add to the list, poor Chaos they always get forgotten...
