Handheld "Microflame Gas Welding Torch", of the same kind used by Luke Skywalker and by the jawas in Part 4: "A New Hope", also used in the series "The Mandalorian". See e.g. https://www.desertscum.org/microflametorch for references. An unopened "micronox" tube (oxygen) is included in the box, but nothing else. Note that this particular copy was NOT used in the filming! The gas welder is not functional, as the knob for butane lacks the pin that makes the hole in the gas tube, but the gas tubes are to my knowledge no longer manufactured. However, it is perfect as a collector's item in a "Star Wars" collection. A small carbon dioxide cartridge can be inserted into the torch for the sake of appearance, so that it looks complete. There are also genuine butane cartridges available for purchase on eBay.
