This is a vintage Coleman Sportster stove model 501-700. This is the green colorway. It was manufactured in June 1962.
The stove has not been used in several decades. The fuel was drained the last time it was put away. And it's been stored in a climate controlled basement.
Please see the photos for more details. The paint is in very good condition. There is some rust on the top.
The box and paperwork are included.
