Growing up in rural south, the only game hangers we had growing up were for rabbit/squirrel. One my uncle used was made from the bail of a bucket. Wood handle moved off center, long side bent 90 degrees and straightened , used the hook/bent opposite end to catch the long end. Picture it as a D shaped wire, the straight side's end sharped, the other end U shaped to hold the straight side and the old wooden handle moved to the middle of the curved section to hold it. Have seen forged ones made the same way.
