Courtesy of Grant Cunningham This is a very rare alcohol stove, made between 1904 and 1906. Jacob Hirschhorn AG was the maker of the well-known AIDA lanterns, a trademark adopted by the company in 1906. Prior to that, the registered Hirschhorn mark was simply the famous leaping stag with the initials "J. H." In 1904, Hirschhorn was granted the trademark "Bengalia" for a "Spiritus-Glühlichtbrenner" ("alcohol mantleburner".) I'm not at all sure what a "mantleburner" is, but it certainly dates this stove! This has an unusually large fount for a spiritburner - 5.25 inches (13cm) in diameter. The stove overall is 6.5 inches (16.5cm) tall, with a removable pierced grate. The stove is all steel, including the previously nickel-plated fount, with brass burner parts. A neat feature are the (4) small jets inside of the main jets, whose purpose is to heat the generator to keep the fuel vaporised. This stove is surprisingly hot and is easy to cook on, having superbly precise flame control.
