How much is a antique wood burning stove worth?

My cousin called and wanted to know if I could find any info for the worth of this wood burning stove he has. I couldn't find any info but I thought I would ask here. It is a a Dixie Belle wood burning stove number 815C, it is made by the Southern Company operative and Foundry Company out of Rome Ga. That's all the info he has and doesn't have a date for it. Any ideas on what it might be worth?
