We have a double door buffalo stove with the top double door oven in very good condition. We were thinking of selling it since we are moving. We can't find any information about it online other than someone else who had posted something on this website about their buffalo stove a few years ago. Their pictures showed that it was painted a shiny black. Ours has the original flat black paint. Does anyone have an idea of how we can find out what it is worth? Thank you.
