OK now I am just bragging . . .

The front end is off the ESCI kit b/c it had the Demag logo cast into the radiator cowl and I feel the headlights and other front detail parts are cast in a much more delicate manor. The main body is the Tamiya/Italeri/Revell offering and finally the PAK 38 gun and gun crew is the sepurb Dragon product. A scratch built gun mount brings them all together and the crew has been greatly repositioned.
Please realize this build was done years before Dragon ever came out with their great kit of this same vehicle. But even in the Dragon kit the one part that fails is their rendition of the gun mount. On the Dragon offering the gun sits too high and this mount is just one big block of cheese with no rearward extending body bracing. It would never work in real life and would tear up the vehicle with continued use!
The folded cloth top is the ESCI part modified to accommodate the spare tire. The ESCI folded top beats all the others for realism and a more correct shape.

Here the gun mount is just dry fitted and the diagonal bracing from the gun mount to the rear corners of the vehicle have not yet been added.
