i have recently aquired an old shotgun, the oly thing that can be read on it is"worlds challenge ejector" stamped on the side. however underneath that stamp you can just make out a previous stamp that says "gold medal wonder". i did a little research and found that the gun may have originally been mfg'd by the h.&d. folsom arm co., this being referenced from the gold medal wonder part; i also found a cross reference to challenge ejector the could have been made for the sears co. by a man named albert aubrey. is there anything more that you may be able to tell me so i can clarify what i acually have?
