I lived in PA when I was a boy, and I remember seeing a number of furnaces like that one. A few were on the way to Grandma's house and there were others near a state park in Central PA where my family along with friends would go on picnics for the 4th and Labor day. Time has dimmed my memory about actual names, but it was over 50 years ago...

Thanks for sharing the picture. The bike's a beauty BTW.
