Lenton/Colledge give in their book on Italian Navy in WW I a ship RAZZOLI ex SJOBORN, bought 18.3.1916, in service 12.4.1916,
deleted from naval service 24.2.1920 and a TRAMONTANA ex NANNA, built 1888.

SJÖBORN sounds at least scandinavian ...

In Lloyd’s List Weekly Index (LLWI) of 18.5.1916 I have discovered SJÖBJÖRN (Sw) sailed Gothenburg 6.3.for Taranto, sailed Swansea 23.3. >>> arrived Naples 10.4. The ship is said to be a steam trawler elsewhere in Lloyd List, but I haven't identified this ship.

Lloyd’s List Weekly Index (LLWI) 1.6.1916 also identifies
NANNA as Swedish, sailing Stornoway-Gibraltar, sailed Cadiz 28.5. >>> arrived Naples 5.6.

I know that a few Swedish trawlers went to Italy:
TÄRNAN ex BOURNEMOUTH blt.1887 Cook, Welton 135gt >> LEVANTE in Italian Navy
HILMA ex BLUE JACKET blt. 1892 Cochrane 148gt, Gadus Fabrikker, Gothenburg >> ZANNONE in Italian Navy, later ZARA and MARIA BAMBINA, last owned in Malta and foundered in 1933.

Anyone able to tell about the origins of SJÖBJÖRN and NANNA (they may well be in LR, but I don't have one on hand of the war years and I think I had looked for them many years ago)? Any Swedish trawlers disappearing during the war without trace, this way they might have gone! Any Swedish sources who could tell about these sales to the belligerant countries (there was some legal problem with neutrality and the sale sometimes as in Norway may have been a bit camouflaged).
