Here are a few 1/6000 scale ship to fill gaps in the fleets. All are Figurehead.
Garibaldi class armored cruisers built by Italy and sold to Argentina and Spain (Pedro de Aragon was cancelled) and British seaplane carriers.
Late war British Ceres and Capetown class light cruisers, and WW1 ships from the Figurehead Argentine and Brazilian fleet packs.
