My wife and I recently purchased a home that was built in 1960. In the basement is a small woodstove that says Forest Oak on the sides, and No 18 on the front above the door. Also,Kelley Woodstove Co,Philedelphia Pa, Patent 1877 is engraved on the top. I tried searching Google but I did not find any useful information about the stove. My chimney sweep checked it out and said it is in useable condition. Can anyone offer any information about this stove?
