A purely selfish move to take images and catalogue the few hundred I have and the hard task to identify these crazy characters has motivated me to start a thread so that some others could join in on my confusion with these illegal entities which now have their own fan club, admittedly mostly the American Market. But I know many of you have some, if not a lot, and thought you might help me out. The Only reference I have are some past papers from the BNS and a book by R Coleman and I am in need of help finding a book??/ by Atkins that the americans are always referring to . Hope it's OK to press on ?
