The 'live' version of this grenade, known as the 'Grenade, Hand or Projector, No. 76, S.I.P. Mk I', consisted of a short-necked half-pint capacity glass bottle filled with an incendiary mixture and closed with a crown cap. The filling itself was made of yellow phosphorous (128cc), water (21cc), benzine (110cc) and a 3.5in piece of crude rubber, which partially dissolved during storage to give the mixture more adhesion on impact. The grenade was invented by Albright and Wilson, and was primarily designed for Home Guard use during the Second World War. It was produced in two forms, one with a red cap for hand throwing (typically up to 30 yards), and the other, with a green cap, for use with the Northover Projector (with an effective range of up to 100 yards). In use, when the bottle struck its target, it shattered, and an instantaneous ignition took place producing a cloud of screening smoke containing phosphorous pentoxide and sulphuric dioxide and an incendiary effect. These fumes were noxious and would force the crew of an AFV to don respirators, thus reducing their fighting effectiveness, and in addition, the incendiary effects may have forced them to abandon the vehicle. The initials 'S.I.P.' stood for 'Self Igniting Phosphorous'.

The "live" version of this grenade, known as the Grenade, Hand or Projector, No. 76, S.I.P. MkI, consisted of a short-necked 1/2 pint capacity glass bottle filled with an incendiary mixture and closed with a crown cap. The filling itself was made of yellow phosphorous (128cc), water (21cc), benzine (110cc) and a 3.5in piece of crude rubber, which partially dissolved during storage to give the mixture more adhesion on impact. The Grenade was invented by Albright & Wilson, and was primarily designed for Home Guard use during the Second World War.
