i found some foto's of the sturmtiger with early or midwheels under it :

That was first and last prototype of sturmtiger ever build.

After prototype, series-produced was start. 12 sturmtigers were build between august 13 and september 21, and 5 were build in december 1944.

So we have 18 sturmtigers, including prototype.

In Sturmtiger repaired Tiger's hull was used. So we have zimm coat on hull, oryignal from late Tiger I, and on the superstructure no zimm coated:

Examples:

This Sturmtiger from 1001 Panzersturmmoerserbatterie destroyed on february 28, 1945
