I missed that DGJ article on W.S. Riley, have to find that one. I have a W.S. Riley, #7,008. There was a thread on the old Internet Gun Club site that answered a few questions I had on it. I'm not a member there anymore and can't view the threads. This gun was where the IGC got the spread eagle logo and banner with "Nothing Without Labour". I can't recall, but I think it may have also provided the name of his shop, Eagle Gun Works. Quite a few patents mentioned in this, including what I'm told is Parson's chopper lump hammer mark. Well made with London proofmarks. I'll just post some photos.
