Jim King did most all of the work in making the kit. This included him hand-measuring the original 1:1 prototype car. Then making the CAD files. He then had an SLA made where he took molds of each side and then put the castings together to make the one-piece body. He then molded that and casted that. From there, one adds the detail parts on, paints it, etc and you have a finished kit.
I have kits available in 3R, 2R, and 3RS. I can even put these together for an extra cost. Kits come with Southern decals, but I can also provide NS decals for an extra cost.
For more info on these kits and future kits I am looking at having produced, see here:
