This kit is a model of a proposed design by the Krupp AG company. The thought was to upgrade the firepower of the Pz IV with the newly designed Panther turret with its 7.5cm KwK L/70 gun. Nothing came from this proposal and the painting schemes are pure conjecture.
This is a multimedia kit comprised of 477+ styrene parts, DS tracks, 1 photo etched parts fret, and much worse set of instructions. They need to be reviewed very carefully before gluing any parts together.
