This is my model of a Jagdpanzer Ferdinand, as several of them were photographed during and shortly after the Battle of Kursk by the Soviet Army in July 1943. This model is based on the Italeri kit of the Jagdpanzer Elefant, which is a rebox of the much older Esci kit. Only a few small changes were necessary to make it into a Ferdinand. The figures are Esci Soviet Infantry.
