I purchase this stove barley used on market place. Question is it has a piece on top that looks like the connection piece that may of came with the stove? Not sure thing is the crimp is the wrong way. The second to last picture shows how it was attached on the stove. It ha another sleeve piece that sits down in so yea not sure if this came with it or what originally.maybe it’s upside down or stove pipe with crimped end goes down into the first shown picture without this piece. Let me know what you think thanks
