Griffin gives this flag for sailing vessels, with an enhanced “o”; the illustration instead follows the Collectors Corner cap badge. Reed shows a wider blue cross and omits the white after the blue funnel stripe.
Lloyds 1912 and Stewart show equal funnel stripes, while the illustration follows black-and-white photographs of Hermelin and Hermion in Merchant Ships 1942. Jordan does not specify stripe widths. Brown 1926 omits the white after the red stripe, and Brown 1929 is unclear.
