Cutaway model of a ‘Ground Amber star parachute M21A1’. This rifle granade is fired by the M1903 Springfield, the M1917 American Enfield or the M1 Garand, with all of these rifles by means of an adepter placed over the end of the barrel
Before firing, the ‘Ground Amber star parachute M21A1’ is unpacked from it’s cartboard container and placed over the adepter. Than the propulsion cartridge is chambered in the rifle. The flare is normally fired in an angle of about 80 degrees upward. With the older models of this rifle grenade the propulsion cartridge was placed in the tail, the tail closed with a cork plug, with later models the propulsion cartridge was delivered seperately. The ground star amber was meant to give a tactical signal by emitting yellow light during a numer of seconds, hanging in the air on it’s parachute.
Parts:
1 – steel tail pipe with ring shaped stabilizer spot welded to the pipe.
2 – Pertinax disc to keep the black powder igniting pellet moist free.
3 – Black powder igniting pellet.
4– ring shaped pyrotecnic delay fuze.
5 – black powder expulsion and flare ignition charge.
6 – Felt washer.
7 – Flare in cartboard container with steel top disc to connect to the parachute.
8 – Parachute with strings, these strings connected to a single steel wire that connects to the top of the flare
9 – wooden stick.
10 – steel lid (painted yellow on top).
Complete length M21A1: 250mm
Diameter : body: 41,7mm, tail ring : 47,5mm
Upon firing the flare by means of the propulsion cartridge, the pertinax disc (2) is pulverized. The gasses of the propulsion cartridge ignite the igniting pellet (3) that ignites the pyrotechnic delay ring(4), which ignites the black powder expulsion charge (5). This pushes the burning flare (7) upward inside the grenade body. To prevent the glued steel lid(10) from obstruction ejection, a wooden stick (9) is placed between the flare an the steel disc, levering it off the grenade body. After ejection the parachute unfolds and the burning flare slowly floats down to earth, hanging on it’s parachute, emitting yellow light.
This rifle grenade was produced in October 1944 by M. Backes‘ sons Inc. (code MBS), a Wallingford Conneticut USA based pyrotechnics company. Regretfully this factory burned down to the ground in 1956.
