Jimmy you could try contacting Clive over at http://historiccoinage.com/default.aspx He might well be able to help you out.
Thanks, I just may. On another note, I'm always looking to add trusted dealer sites to my search lists, do you know of any additional sites in he UK covering hammered british coins?
Have you tried this one - English Hammered Coins this one - History of British Coinage And I imagine you have already, but if you haven't - check out the Resources section. There's stuff there you won't find anywhere else.
Class c confirmed. Wren's book arrived this week; between the book and this thread I am confident it's Vc. Thanks all!
