MS Warszawa II was never completed as a passenger ship. While being built in Dutch shipyards in 1940 she was captured by the invading Germans and later used as a U-boat tender. After the war she was returned to Poland but was in a very poor condition so they scrapped her; only her engine was re-used in a cargo ship.
The drawing is based on the original project plan and some artist impression of a completed vessel.
P.S. Feel free to post your drawings of never built merchant ships here in this thread.
