Deactivated 12 Gauge Signal Cannon by Winchester Repeating Arms of USA and made between 1901 and 1958. Opening breach and working firing mechanism and in very good condition. Approximately 18 inches long and very heavy. Made of caste iron, these were originally intended to warn other ships or boats in foggy conditions. However, they are now more often used to start races at yacht clubs. Would make a splendid conversation piece. All deactivated weapons sold by D and B Militaria are deactivated in the United Kingdom and hold London or Birmingham proof marks and a certificate stating that the weapon has been deactivated correctly and is legal within the U.K.
