Hello and thanks for your reply. I was mostly just looking for opinions of them. I cannot do a bearing test because it is through ebay. I did all kinds of searches. The only thing i came up with is a reference in a response to someones elses post here on the I forge site. In the photos of it I believe I can see the forge weld line of the hard face on the body, but it is not super clear and I am asking the seller as well. Your comment that yours has decent rebound is what I was looking for. The one I am looking at clearly says 'warrented, solid wrot, some kind of deep 'P' mark, john powell, birmingham, england' - each on its own line.
