The early Scottish Line flag resembles the Scottish Royal Standard: yellow with a red lion rampant inside a red frame.
Talbot-Booth omits the frame, while noting that the flag once had a Scottish-style border.
Brown’s editions from 1943 restore a double frame but make the lion passant. A 2008 photograph of Alltrans confirms the funnel.
Stewart and The Log likewise show the double frame but retain the lion rampant.
The National Maritime Museum flag is dated about 1951 and is the basis of Bakker’s FOTW illustration.
