Sources disagree over whether the red bands end straight or forked beside the letter. Stewart and, less clearly, US Navy show forked ends, while Watt gives straight ones; their presence on the funnel is uncertain. Funnel and flag lettering also differ. Watt traces the depiction to a 1953 Japanese book copied through Styring, considers the funnel more accurate from photographs, and questions the flag’s different S. A 1960s monochrome advertisement has a conventional letter.
Brown shows unbroken bands with a squared black S over them. Watt identifies N111 as incorrect.
This funnel was adopted after the Second World War. Its two bands represent ni in kanji and katakana; S may stand for the second syllable san or for steamship.
