Original Item: Only One Available. This is an excellent totally inert example of a 1944 dated No. 36M MkI Grenade known as the "Mesopotamian" variant due to its shellac-coating which was designed to keep moisture and humidity out of the detonator's fuse. The No. 36M MkI was the British army's standard hand-grenade during WWII. This wonderful example is complete with internal parts (no explosives!) original paint, including the three red Xs along the side indicates that it is the waterproofed No.36M model.

Mills bomb is the popular name for a series of prominent British hand grenades. They were the first modern fragmentation grenades used by the British Army and saw widespread use in World War I.
William Mills, a hand grenade designer from Sunderland, patented, developed and manufactured the "Mills bomb" at the Mills Munition Factory in Birmingham, England, in 1915. The Mills bomb was inspired by an earlier design by Belgian captain Leon Roland. Roland and Mills were later engaged in a patent lawsuit. Col. Arthur Morrow, a New Zealand Wars officer, also believed aspects of his patent were incorporated into the Mills Bomb. The Mills bomb was adopted by the British Army as its standard hand grenade in 1915, and designated the No. 5.
The Mills bomb underwent numerous modifications. The No. 23 was a variant of the No. 5 with a rodded base plug which allowed it to be fired from a rifle. This concept evolved further with the No. 36, a variant with a detachable base plate to allow use with a rifle discharger cup. The final variation of the Mills bomb, the No. 36M, was specially designed and waterproofed with shellac for use initially in the hot climate of Mesopotamia in 1917, but remained in production for many years. By 1918 the No. 5 and No. 23 were declared obsolete and the No. 36 (but not the 36M) followed in 1932.
The Mills was a classic design; a grooved cast iron "pineapple" with a central striker held by a close hand lever and secured with a pin. According to Mills's notes, the casing was grooved to make it easier to grip and not as an aid to fragmentation, and in practice it has been demonstrated that it does not shatter along the segmented lines. The Mills was a defensive grenade (meant to be thrown from behind cover at a target in the open, wounding with fragmentation, as opposed to an offensive grenade, which doesn't fragment, relying on short-ranged blast effect to wound or stun enemy troops without endangering the exposed thrower with fragments, which travel a much longer distance than blast alone. With fragmenting defensive grenades, after throwing the user had to take cover immediately (however, in spite of the designations, "defensive" grenades were frequently used offensively, and vice versa. A competent thrower could manage 15 metres (49 feet) with reasonable accuracy, but the grenade could throw lethal fragments farther than this. The British Home Guard were instructed that the throwing range of the No. 36 was about 30 yards with a danger area of about 100 yds.
The heavy segmented bodies of "pineapple" type grenades result in an unpredictable pattern of fragmentation. After the Second World War Britain adopted grenades that contained segmented coiled wire in smooth metal casings. The No. 36M Mk.I remained the standard grenade of the British Armed Forces and was manufactured in the UK until 1972, when it was completely replaced by the L2 series. The 36M remained in service in some parts of the world such as India and Pakistan, where it was manufactured until the early 1980s. Mills bombs were still being used in combat as recently as 2004 e.g. the incident which killed US Marine Jason Dunham and wounded two of his comrades.
The No. 5 Mk. 1 was the first version. The explosive was filled through a small circular plug on the upper half, the detonator assembly was inserted into the centertube of the mills through the bottom of the grenade body via the baseplug, the striker and spring is held in tension through the middle by the lever that was held down on the lugs (ears) located on the top of the grenade body via a split pin and ring called the safety pin/ pullring. It was first issued in May 1915 and entered general issue when mass production caught up a year later in 1916.
The No. 23 Mk. 1, the hand/ rifle-grenade ' had a baseplug drilled with a threaded hole for a rifle launching rod . The No. 23 Mk.II had a new style iron baseplug that was easier to tighten with the fingers without the need for a spanner.the No. 23 MkIII was a new style body with a larger filler hole plug and more solid lever lugs/ears but retaining the MkII style plug.
The shellac-coated "Mesopotamian" variant (No. 36M MkI) was designed to keep moisture and humidity out of the detonator's fuse. The No. 36M MkI was the British army's standard hand-grenade from the 1930s to 1972.
A green band around the middle originally indicated an Amatol filling (1915–1920s), while it later indicated a Baratol or Trotyl filling (1920s–1970s).
A pink band around the middle indicates an Ammonal or Alumatol filling. (Alumatol is defined by the Dictionary of Explosives, pub 1920 as 'a mixture of ammonium nitrate, TNT and 'a small quantity' of aluminum power.) A red band around the base plug on the bottom indicated the detonator was already installed and that the grenade was live. Three red Xs along each side indicates that it is the waterproofed No.36M model.
