I have a Bergstrom Bros. & Co. wood stove with the text “Royal” and “Winner” and “224 N” on the front door plate. Manufactured in Neenah, WI. The only thing I have come up with in research is that the company went bankrupt in 1915 so this stove is at least 100 years old. Trying to figure out what it is worth so I can sell it and install a more efficient wood stove. Any help would be greatly appreciated!
