Original Item: You’re Not Going To Believe This: IMA has found a few sets of night sights for the Vickers Mk I Medium Machine Gun. We have three different sets, including TWO DIFFERENT FIRST WORLD WAR versions. The first two types were luminous, using small glass vials of radium. After World War 1, the machined attachment bases for both front and rear sights were converted from the original luminous sights of World War 1 to the nonluminous sights of World War 2, so very few of the original sights survived.
Set No. 2: World War 1. This set includes a No. 2 front sight and adds a shield to the rear sight. Both sights were originally of the luminous type, although the radium that produced the luminosity has now expired in the front sight, and the radium vials have been removed from the rear sights. Both components are contained in a small fitted steel box.
