SLOMAN NEPTUN SCHIFFAHRTS AKTIENGESELLSCHAFT.

The black funnel carries a blue–yellow biband inherited from Neptun. The blue flag follows Robert M. Sloman’s white three-towered castle, with six-pointed stars above the outer towers but five-pointed stars in the corners. Rosanoski leaves open whether the latter reflect an error, a change or a connection with related F.L. Sloman’s flag. Nüsse assigns the illustrated flag to Robert M. Sloman.
