H689 was identified from an undated H. Carly flag chart published after March 1889 and before April 1899.
H690 shows a red flag with a central white five-pointed star containing a blue capital H, from Deicken und Behrmann’s summer 1897 supplement. Rosanoski notes that either the two sources differ over the H’s colour or one is incorrect.
