I am the historian for a collectors society. Recently I came into possession of a Webley revolver Q141. The Webley Mark IV in 455 was made between 1899 and 1901, inspected by the Sparkbrook Factory inspector and proofed. Service marks in and out Serial numbers on Cylinder and frame match.
My Theory is Q 141 denotes the regiment part of the 4th Imperial Bushmen's Regiment in the Boer War Queensland Thought and info appreciated.
