TheWelrodis a Britishbolt-action,magazine-fed,suppressedpistoldevised during theSecond World Warby MajorHugh Reevesat the Inter-Services Research Bureau (laterStation IX). Station IX, being based inWelwyn,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 byirregularforces andresistance 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]
Development
[edit]The nameWelrodcomes from the custom of naming all clandestine equipment devised at Station IX in Welwyn starting withWel,e.g.,Welbike,Welman.[1]A document produced towards the end of the war ensured that the right people were properly credited for their inventions at Station IX. This document identifies MajorHugh Reevesas the inventor of the Welrod. He was also responsible for other important designs, including thesleeve gun,which was similar to the Welrod, though single shot and made to conceal up a sleeve.[2]
The Welrod was used primarily by the BritishSpecial Operations Executive(SOE) but was also used by the AmericanOffice of Strategic Services(OSS) and Resistance forces.[citation needed]
The Welrod was a "sanitised" weapon, meaning that it had no markings indicating its manufacturer or country of origin; it was marked only with a serial number and some inscrutable symbols and letters.The Birmingham Small Arms Company Limited(BSA) confirmed that they manufactured some Welrod pistols but that they put no markings at all on them, so it is likely that any markings were added by the British military after delivery.
The original Mk1 Welrod was a bolt-action design.[3]While 500 were ordered, its not clear if it ever got beyond the prototype stage.[3]The Welrod Mk II, chambered for.32 ACPwas the primary model.[1][4]Due to poor field results, the Welrod 9mm Mk I was subsequently developed using9×19mm Parabellumrounds.[5][4]
Design
[edit]
The Welrod takes the form of a 1.25-inch-diameter (32 mm) cylinder, about 12 in (300 mm) long.[6]The rear section of the cylinder contains the bolt, the middle section, the vented (16–20 ports) barrel and expansion chamber for the barrel and the front section, the baffles and (rubber) wipes of the suppressor. There is aknurledknob at the rear that serves as the bolt handle, which unlocks when rotated 90 degrees. The magazine doubles as the grip and can be removed for ease of hiding. The exclusion of a pistol grip was apparently done to help conceal the weapon's purpose and in some groups it was called a "bicycle pump" due to its innocuous look with the magazine/grip removed.[1]
The Welrod is provided with sights marked with luminescent paint for use in low-light conditions.[1]The Mk I manual states: "It is accurate up to 30 yd (27 m) in daylight or 20 yd (18 m) on a fairly light night but is most effective when firedin contact with the target".[7]The muzzle end of the gun is ground slightly concave to minimise noise during a contact shot; this may have also improved grip against the target, decreasing the chance of missing.[1][8]
The ported barrel of the Welrod serves two purposes, it releases the powder gases gradually into the rear of the suppressor, reducing the sound of firing and it reduces the velocity of the bullet tosubsonicspeeds (especially important in the 9 mm version since the standard 9 mm loading issupersonic). The metal baffles and rubber wipes that follow the barrel serve to further slow the gases of firing, releasing them over a longer period of time and avoiding the sharp explosion that occurs when high pressure powder gases are suddenly released to the atmosphere.[1]
The Welrod uses a bolt-action design because it is simple, reliable and quiet. The bolt-action has only the noise of the firing pin hitting the primer, and the bolt can be cycled quietly.[1]Magazines of six and eight rounds were produced.[citation needed]
Operation
[edit]The pistol is manually operated using a rotary bolt, locking with two lugs. Loading is performed with a pull/push action using the round knurled knob to the rear of the weapon. The trigger is single stage with a simple safety at the back of the magazine housing. The detachable single stack magazine contains six or eight rounds (depending on calibre) and serves as a pistol grip with the bottom part enclosed by the plastic cover.[1]
In 2002, Small Arms Review tested the Welrod (in.32 ACP) and found a 34-decibel noise reduction compared to a control pistol with a same length (3.25 inch) barrel for a final 122.8 decibel value. Earlier sound measurements did not meet the standards in place in 2002. According to Small Arms Review, the lower earlier measurements were "Undoubtedly [...] a function of the available measuring equipment (including excessive meter rise time)". A fully refurbished Welrod sounds quieter than a CO2pellet pistol, with Philip H. Dater calling it "Hollywood quiet". The Welrod's sound is almost imperceptible at 15 feet in a quiet environment and it would be inaudible to the operator in a noisy environment where the muzzle is in contact with the target.[9]
Use
[edit]There was a plan in 1943 to drop Welrods into German-occupied territories for the mass assassination ofSchutzstaffel(SS) and Gestapo officers and soldiers within a one-month period by resistance units. This plan was possibly delayed or called off in the aftermath ofOperation Anthropoid,the assassination ofReinhard HeydrichbyCzech resistanceforces.[1]In the wake of his assassination, an estimated 13,000 civilians were arrested and interrogated, 5,000 civilians murdered in German reprisal killings and the villages ofLidiceandLežákydestroyed.
The Welrod was used in Denmark during the war as well as being dropped in several other countries and is reported to have been used during the 1982Falklands War,throughoutThe Troublesin Northern Ireland and during operationDesert Stormby BritishSpecial Forces.[1][5]Welrod guns were also found in weapons caches fromOperation Gladio.[10]The Welrod was also used byUS Army Special Forcessoldiers assigned to Detachment 'A' Berlin during the Cold War[11]and byMACVSOG.[12]
