The NC-1 was a French design created after World War I. Tests proved the tank to be unsatisfactory and it was not adopted into French service, however it was sold on the export market as the NC-27. Sweden bought one which became the Stridsvagn fm/28, Poland also bought a handful that may have actually seen combat. All these designations are identical so this model can be built to represent any of the above.
