SERVICE COMMUN D’ARMEMENTS DESSERVANT L’OUEST AFRICAIN.

Both black and blue funnels were used, each with square white SC letters, possibly derived from Denis Freres. The white house flag shows a blue funnel divided by eighteen white lines into sectors of varying size, with a black band bearing SCADOA in white. That depicted funnel is not known to have been used on a ship.

A second white flag bears a circle made from twenty-four very narrow light-blue lines with wider white gaps, overlaid by a dark-blue seahorse. Below is SCADOA in dark blue, underlined light blue. Its purpose is unknown.
