The Welrod is a British bolt-action, magazine-fed, suppressed pistol devised during the Second World War by Major Hugh Reeves at the Inter-Services Research Bureau (later Station IX). Station IX, being based in Welwyn, gave the Welrod its unusual name, being derived from "Wel" from "Welwyn" (a prefix used by covert equipment designed by Station IX) and "rod", gangland slang for gun, as a way to obscure its purpose.^[1]

Designed for use by irregular forces and resistance groups, the Welrod is an extremely quiet gun thanks to its integrated suppressor. Approximately 2,800 were made in wartime and perhaps 14,000 in total when post-war examples are included.^[1]
