Filipinka

Filipinka (also Wańka, Perełka) was an unofficial, yet common name for the ET wz. 40 hand grenade produced for the Armia Krajowa during World War II in occupied Poland.

It was designed by a former worker of the Rembertów Polish Army munition works, Edward Tymoszak (hence the ET abbreviation). It was partially based on his pre-war design of an ET wz. 38 anti-tank grenade.

The Filipinka was an offensive impact grenade, cylindrical in shape. In the upper part of the shell a screw for the fuse was located. Coating of the first series (roughly 4,000 produced) was made of Bakelite, which shattered without producing fragments like a metal-bodied grenade. Later the shell was replaced with a metal impress. The filling was composed mostly of home-made explosives, either cheddite or ammonal. At times explosives from German air bombs and artillery shells, as well as British plastic explosive delivered through air bridges was used. The grenade was equipped with a contact fuze which functioned on impact with the target.
