BISSMARK-LINIE K.G.

A painting of Malmö dated 1900 confirms the sky-blue shade, but the forward portside view cannot establish whether the funnel bands end aft in the swallowtail shown in B959.

The flag is a horizontal blue-over-yellow swallowtail with a red serifed “B” centred in the main body, excluding the tails.

Mitchell places the horizontal arm of the funnel’s “B” on the blue; Rosanoski doubts that the distinction is significant.

The country/city concatenation is repaired to Germany, retaining the exact Hamburg-Altona raw text. The 1898 origin, GmbH/KG succession and postwar fleet continuity remain unestablished.
