The design dates from the 1860s, and is attributed to Louis Dolne, The gun was manufactured until the end of the 1800s. Called the Apache revolver after the notorious French criminals called Les Apaches. The weapon is designed to fold up into a pocket , incorporating a brass knuckleduster , a pepperpot revolver and commonly a knife , the one we have seems to have lost its knife. There is no gun barrel , rounds fire from the cylinder so its range and accuracy are limited but it is a close combat weapon. Most versions have no safety devices or trigger guard so a chamber left empty under the hammer prevented unfortunate accidents .The one the museum owns is shown open and closed . To reload it was necessary to remove the cylinder , given the use of the weapon this was not a major issue . Generally they were pinfire and made in Belgium . The gun is marked L Dolne Invur serial number 5541 , Dolne was based in Leige .
