X-100 MYSTERY SPACE DART GUN - ARLISS - USA

Stubby rounded plastic space gun with dome bulges at the front. Shoots darts. The main selling feature was the fact that the darts have darts that can be filled with talk powder. The dart suckers have perforations: when they strike a target the talk stains the surface. Available in a range of colors: Burgundy and silver shown. 1950s. See also the X-200 set.

Probable sighting in a 1956 advert.
