The blue flag has a white three-towered castle, six-pointed stars above the outer towers and in each corner. Reed shows the stars and a cross above the towers, whereas Nüsse, Griffin, Stewart and Mobil use five-pointed stars. Nüsse’s version may instead be the later Sloman Neptun flag. The black funnel has a light-green band close to the top. The subsidiary used the same livery; some ships wore Geest colours in the 1960s.
This blue flag has the white three-towered castle and, in each corner, a small white circle bearing a blue ring around R, M, S and JR respectively. Brown 1934 substitutes H for JR.
