Don-Kuban State River Steamship Co. — historical pennant
image by Victor Lomantsov, 12 Aug 2000
A pennant was authorised by decree on 29 August 1924, without further detail in the note. Victor Lomantsov’s FOTW flag was based on 1970s magazine evidence; he dates adoption to the 1920s and thinks use continued into the 1990s. Riverships supplied no flag in the 2009 consultation.
No verified modern Kubanriver use or succession.
