First, Welcome to G&G. If possible a few more photos of any markings and the firearm out of the case may help. A quick search did not turn up anything on the name J W Edon, but I am sure we have somebody here that will (hopefully) know more than I do. I am guessing that what is there is a take down muzzle loader? Either way it does look nice. I realize this probably won't help but welcome anyway
