Looking for Bicentennial Sunfish

When my grandma couldn't live on her own anymore and had to sell her home, the family can't remember what became of her Bicentennial Sunfish that had been in the family for about 30 years. Maybe it was sold at a yard sale, maybe a neighbor bought it, maybe someone made off with it. I'd like to replace it if I can because I think she'd like that. I'm in the Atlanta area, near Lake Allatoona, and am really just beginning to put out feelers.
