The Cameleon is a Czechoslovakian concept revolver chambered in .44 Magnum.
The Cameleon was a concept revolver designed by Czechoslovakn ice rink technician Karel Michalek. Michalek had wanted to make his own handgun, but was limited by government restrictions. In 1989, Michalek decided to construct a concept gun out of wood and epoxy resin. Michalek's concept revolver is currently in the possession of the NRA National Firearms Museum collection.
