The FOTW illustration is green with a red disc towards the hoist, containing white HB above PG and surrounded by a thin rope. Schneider notes that the cited Kludas account names the steamship company, yet the flag has P rather than D, perhaps for Paketfahrt. Rosanoski says the cited illustration should instead look like H731.
This attribution is an assumption: Rosanoski considers that Mathies wrongly assigned the flag to Hamburg-Brasilische Dampfschiffahrt-Gesellschaft and that Kludas repeated the error.
Packet, passenger wording and steamship attribution remain disputed.
