Terraplane hood ornament...what year? *pic*

My aunt recently asked me if I knew what kind of car this hood ornament came from that my uncle had before he passed away. Well I asked around and was told that it came from a Terraplane but could not find out what year. Any ideas by looking at it? A range would be helpful if a specifc year can not be determined. Any idea how much it might be worth? I thought about putting it on ebay for her. Its in pretty good condition...there seems to be some pitting on it that looks like the size of a sand grain. Not sure if that can be buffed out. Any help is appreciated.
