My best memory says no. I recall the "E" as being the first model in Africa, which you can't convert your "C" into as there are some large external differences.

In my file compiled to produce the box illustration for this kit, I found a dozen photos of this vehicle taken by combat photographer Falk in 1943. The photos are described as "Russland".
Most shots deal with the fitting of the gun while several show the left side as it was completing conversion (welds are unfinished, etc.) It appears to have been a Panzer IIC that it was based on. In the background are several Marder II giving the image the appearance of a workshop.

Two other unattributed photos show such a completed vehicle in service. There are enough differences between these two photos to suggest that more than one were produced but it could be just as easily explained that these were further upgrades of the much photographed vehicle.

One source mentions that this vehicle served with 23rd Panzer Division in the fall of 1943. This would put them near the Dneipre river in southern Ukraine. The 23rd had 128 Panzerjager unit with 14 75mm self-propelled vehicles, possibly Marder II based on Panzer II chassis.
