AFS doesn't show many of it's "Armoury" products online. They were kind enough to scan a page from their old print catalog and send me that and a list of discontinued items.The pommels I've marked in red are not available. Everything else is available, and I've tracked down photos so you can see what some of those look like in the flesh.
Match those part numbers to prices here: http://www.amfence.com/html/parts_armoury.html and order by phone.
I've just ordered three "Claymore" pommels at $35 each. I'm thinking that is likely to be the most useful. I'll post photos here ASAP.
