Brown’s 1982 account gives C68 for former Coe vessels and C568 for former Metcalf vessels, with the flag of Booker Line, Coe’s owner. Rosanoski bases the dark blue on Mitchell’s funnel; the letter’s shape may vary.
Brown’s 1995 edition assigns this livery to dry-cargo vessels.
Brown reports this funnel on some ships, describing company initials without defining the letters.
