A pennant was authorised by decree on 29 August 1924, without design detail in the cited note. Lomantsov recalls this flag in 1970s magazines, dates its adoption to the 1920s, and believes it remained in use into the 1990s.

This flag is supplied by riverships.ru.

Mitchell shows the ensign, possibly indicating its use as a house flag. His three vessel line drawings omit the funnel.

Dubai Fortune of the Gulfruss Shipping subsidiary, photographed from starboard on 7 February 2006, appears to carry a very dark-blue marking with CP letters, although the C could be G. STK 1026 of the parent company shows a brighter blue in a starboard photograph dated 14 December 2005.

Amur 2526 photographed from port on 29 June 2008 supplies a possible replacement or alternative design. Rosanoski transcribes the website lettering as CPN for Cebephoe peyhoe napoxogcmbo, without translating the last word. STK 1029 photographed from starboard on 6 September 2012 shows the emblem in light sky blue.
