"ADRIA" ROYAL HUNGARIAN SEA NAVIGATION CO. LTD.

The pre-war sources differ in detail. Griffin 1895 shows a white oval with a black-outlined foul anchor, a crown above and a scroll below. Lloyds 1904 gives the emblem in red, with a mitre-like crown touching the anchor, possibly a red “A” across the stock, and a red scroll with white lettering. Lloyds 1912 has a blue anchor, while the crown and scroll resemble printing blots or parts of the cable. Reed 1912 has a larger oval touching the flag’s top and bottom, an apparent red “A”, and a red scroll with black letters. Rosanoski cannot read the scrolls; in Reed 1901 he tentatively sees two words roughly like “Pamoniz Mayavalu”.

The corrected FOTW/FAME portrayal is light green with a vertical white oval, containing a red “A” over a blue cabled anchor. An earlier portrayal made the oval horizontal. Heimer considers the crown probably St. Stephen’s and guesses that the scroll might read “ADRIA” or “FIUME”, but omitted these unclear details from his earlier drawing. He thinks the letter and cable are red and the anchor blue. Rosanoski notes that the crown and scroll only become recognisable by comparing the different printed sources.

For the post-1918 Italian company, Larousse Commercial 1930 shows blue with a red saltire, its arms one-fifth of the flag’s width, and a yellow anchor without rope bearing a yellow “A”. The flattened apex of the “A” runs parallel to and immediately below the anchor stock; the letter rests entirely within the saltire. The anchor occupies about one-third of the flag’s length and almost its full width. The funnel is black. Jarig Bakker’s account of All about Ships and Shipping 1938 instead gives blue legs to the “A”, an anchor two-thirds of the flag height and a yellow five-pointed star above it. Rosanoski’s copy shows yellow legs and the star in position. Jan Mertens had noticed a tiny yellow speck in the 1930 image but initially took it for a printing fault.

Heimer’s later portrayal includes the yellow anchor, “A” and five-pointed star over the red saltire. He suggests, with qualification, that the star was Fiume’s “star of freedom”, replacing Hungarian emblems and lending support to the earlier crown interpretation. Mertens suggests that the blue might refer to Italy and that the central emblem survived in an adapted form; his suggestion of involvement in forming Adriatica di Navigazione remains separate from the Tirrenia accounts.

The long document mixes prewar Hungarian and postwar Italian companies and debates rival flag attributions. A single Austro-Hungarian country cannot be applied to later Italian liveries. A310, explicitly cited here, is mapped to Costeira elsewhere; no source mapping was altered.
