The first funnel is black with a white I superimposed on a white O. The initials stand for International Ouvrière, and the emblem resembles the Greek letter phi. Black-and-white photographs show variation in its height: it is placed high on Biscarosse and somewhat lower on Guilvinec.
The second funnel, adopted after re-establishment and first used on Owendo, is buff with a black top, separated by a red band narrower than the top. A photograph of Kerkena confirms the band’s portrayal.
