Yes indeed, the Conte Di Cavour had 18 × single 120 mm (4.7 in) guns, so the extra "1" is just a typo. Great seeing this kit un boxed, thank you kindly!
Pity they chose the Etna. It never entered service. Italy had so many fantastic cruisers to depict, dont know why they picked a fantasy vessel. The Zara or Fiume or Bolzano maybe.
This is the most disappointing product Warlord ever made (as far as I know their products): A Carrier that never saw service, a fantasy AA-Cruiser and an outdated WWI battleship. There‘s the very nice heavy cruiser ‚Pola‘ but for each historical mission in the book you‘ll need 3 of those. For a long time these Cruisers weren‘t availiable separately. Now you can buy them seperately but they charge 20$/19€ for one. No love for the italians at Warlord in my view. Sadly! I got my Regia marina for about 50$/46€ by getting STLs an let them be printed in resin. And I‘ve got the COMPLETE regia marina fleet: 6 battleships, tons of cruisers, 40 destroyers and 50 subs. Sideeffect: In this way I‘m able to avoid these annoying Warlord Ship-Bases which look like swim tires.
