With that pushed in wing tip, the value, whatever it is, decreases. That is a point at which the eye goes immediately. Rather odd that they made bookends out of these when the style could have been changed to have a half pheasant for each bookend but there it is with an odd piece attached to the side in the Worthpoint example.
I would guess they sold this as just a decorative pheasant because they already had the mold. My guess is pot metal or white metal with a brass finish. Dodge was mainly a trophy maker and most of those pieces are of a cheap cast metal.
