Hi Steve,
The tamiya model was intended to be a version of the Walter Wolf's countach (founder and owner of Walter Wolf Racing, a formula 1 team). The original model should have more decals with the Walter Wolf and maple leave logo but i didn't like to much. Also, the original car had rear spoiler but i cutted it. Only 3 Walter Wolf Countach were made (one red, one blue, one navy blue) and were made by Walter request, the cars had some improvements from the serial car.
I didn't intend to make this exact version, i wanted a regular Countach without rear sopiler and I just put this small decal because i think it would look good.
