RARE Vintage IMAI 1/150 NAPOLEON – First Screw Battleship – B-401 – Complete & Unbuilt. The world’s first purpose-built steam battleship and first true screw battleship, designed by Henri Dupuy de Lôme. This is the large 1/150 display kit, not the small waterline version. This kit is famous for its size and detail and has been out of production for decades since IMAI closed. Later reboxed by Aoshima, the original IMAI box art and tooling is the most sought after. Condition – From Photos. Open box, verified as pictured. This kit appears complete and unbuilt. Hull halves are unglued and unpainted, with crisp wood grain and gun port detail. Decks and all smaller sprues still in original factory sealed bags. Original brown instruction booklet / rigging guide and rigging plan included. Box in good vintage condition with light storage wear and edge wear, no major crushing, colors still strong. What you see in photos is what you get. No start, no paint, no glue.
