Developed in Cedar Rapids, Iowa, by Lebeda Engineering LLC, a firm which has created props for multiple movies including the cyanide injecting silver dollars used in the movie "Bridge of Spies". The ring itself features a bright brass band with the remaining parts finished in nitre blue, including the five-shot, hand rotated cylinder. The revolver is chambered for a 4.5mm (.177) caliber brass pinfire cartridge. This unique/obsolete cartridge makes this neither a firearm, nor is it considered an "any other weapon". Includes a velvet wrapped jewelry style case with a small copper plaque detailing the family history of Czech Lebeda gunsmiths on the lid and contains a screwdriver and five pinfire cartridges.
