ITALIA DI NAVIGAZIONE S.P.A.

Photographs support the I7 funnel, but Ships & The Sea says the earliest funnels lacked black tops. The spacing of green and red bands varies between vessels, including Birmania and Maria. The US Navy book edges the flag’s white half in red.

The flag combines Genoa’s red cross with Trieste’s white pole-arm emblem on red. Rosanoski calls the latter a ranseur or spearhead and says no other source supports yellow for it; Al Fisher likewise notes Stewart’s white spear. The Observer description calls it a halberd, while John Ayer distinguishes a ranseur from an axe-headed halberd. A photograph of Leonardo da Vinci supports the I8 funnel, and the Brazil website’s 1950 livery has a broad red top. The earlier FOTW name Italia di Navigazione S.r.l. is discussed as the same line, although the initial caption questions the identification.

S. Caboto’s red funnel top is described as twice the width of the green band. Photographs show narrower diagonal bands at the aft end on both sides, with the green diagonal following the funnel’s rear edge before ventilation slats interrupt it. Rosanoski questions how far the apparent diagonal angle reflects the funnel’s taper.

The National Maritime Museum flag is dated about 1951 and measures 762 by 1219.2 mm. Its Genoa–Trieste design appears reversed. Jarig Bakker suggests that the museum may have misidentified a Lloyd Triestino flag; the attribution remains qualified.

I9 is recorded in Brown 1995, no. 420.
