The 1/32 scale AT-AT was created by scratch modeler Dimitri Kaliviotis. (Update: Link removed because the website is gone.)
This entry is a heavily modified ATATRON kit. The ATATRON kit is a garage kit which is not commercially available but a few models have been made over the years. I managed to get hold of one because I was commissioned to put some finishing touches on the prototype model and to make the molds for it, so later I was given one of the castings as a “bonus gift”. However the ATATRON I got was one containing mostly reject cast pieces. So Instead of repairing the reject/miscasts I decided to use those imperfections in my favor.
