E-014 is a Polish filter specifically made for the Polish People's Army. It is a licensed copy of Soviet EO-14 made in Poland. It was typically given an olive coat of paint in contrast to the brownish/bronze paint its Soviet equivalent was known for. The shape of the filter itself went on to inspire other Polish filters, such as FP-2131 and FP 203. Attached are also the textures of the soviet version of the filter, E-012.
