Found this in a local shop. The box cover is rough but is in unused condition. Consists of the lantern assembly, plus the stove head. Included is the Stabilizer Base # 53482 for propane bottle and Converter Valve # 53481 for conversion from butane or propane. Lantern is rated at 100 watts and the stove at 3,700 BTU's. The butane tank cover has a "made in Italy" sticker on the bottom. Instructions for the set plus a "Kemper Group Welding Gas" owners manual in multiple languages. Backpacker Magazine from September 1986 mentions this set. This will look great on the display shelf.
Wow ! That's a nice find ! As @fyrwokr stated, see the 1986 advertizement of this special combo, at page 86 from a back issue of Backpacker magazine.
