Totally inert and demilitarized according to BATF guidelines with hollow body and inert fuse. This is a lovely \"relic\" condition round for the British WWI Stokes mortar, which is a \"high explosive\" type canister round. These early mortars were made in various different configurations, which changed as the war went on. Unlike later designs these do not have any fins on the back, for stabilization, making it definitely a very primitive design. The front fuse has TWO pull pins that must be removed in order to arm it. This example is missing the pins and is heavily oxidized from being ground dug. Measures approximately 18 1\/2 inches in length.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNot available for Export.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCondition is good, considering that it is almost certainly a battlefield pickup or ground dug example. It was disarmed but was not cleaned, but it has a lovely patina. Both the bottom and top ends of the tube unscrew to show the empty internal explosives chamber.\u003c\/p\u003e\n\u003cp\u003eA nice relic example of a hard to find piece of WWI British ordnance, ready to display!\u003c\/p\u003e\n\u003cp\u003eThe Stokes Mortar was a British trench mortar designed by Sir Wilfred Stokes KBE that was issued to the British and U.S. armies, as well as the Portuguese Expeditionary Corps, during the latter half of the First World War. The 3-inch trench mortar is a smooth-bore, muzzle-loading weapon for high angles of fire. Although it is called a 3-inch mortar, its bore is actually 3.2 inches or 81 mm.\u003c\/p\u003e\n\u003cp\u003eThe Stokes mortar was a simple weapon, consisting of a smoothbore metal tube fixed to a base plate (to absorb recoil) with a lightweight bipod mount. When a mortar bomb was dropped into the tube, an impact sensitive primer in the base of the bomb would make contact with a firing pin at the base of the tube, and ignite the propellant charge in the base, launching the bomb towards the target. The warhead itself was detonated by an impact fuse on reaching the target.\u003c\/p\u003e\n\u003cp\u003eThe barrel is a seamless drawn-steel tube necked down at the breech or base end. To the breech end is fitted a base cap, within which is secured a firing pin protruding into the barrel. The caps at each end of the bomb cylinder were 81 mm diameter. The bomb was fitted with a modified hand grenade fuse on the front, with a perforated tube containing a propellant charge and an impact-sensitive cap at the rear.\u003c\/p\u003e\n\u003cp\u003eRange was determined by the amount of propellant charge used and the angle of the barrel. A basic propellant cartridge was used for all firing, and covered short ranges. Up to four additional \"rings\" of propellant were used for incrementally greater ranges. The four rings were supplied with the cartridge and gunners discarded the rings that were not needed.\u003c\/p\u003e\n\u003cp\u003eOne potential problem was the recoil, which was \"exceptionally severe, because the barrel is only about 3 times the weight of the projectile, instead of about one hundred times the weight as in artillery. Unless the legs are properly set up they are liable to injury\".\u003c\/p\u003e\n\u003cp\u003eA modified version of the mortar, which fired a modern fin-stabilized streamlined projectile and had a booster charge for longer range, was developed after World War I; this was in effect a new weapon.\u003c\/p\u003e","brand":"Original Items","offers":[{"title":"Default Title","offer_id":42679850172485,"sku":"ONSV25LBM033","price":250.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1524\/1342\/files\/ONSV25LBM033__05.jpg?v=1755338336","url":"https:\/\/www.ima-usa.com\/products\/original-british-wwi-inert-3-inch-stokes-mortar-round-in-relic-condition","provider":"International Military Antiques","version":"1.0","type":"link"}
