I will quote the Gold Portfolio, "For promotional purposes, another turbo engine was developed by legend (as pictured). This particular engine, now owned by Ed Bernstein, co-owner of Delorean One, was displayed around the country." The pictures in the article depict an engine that is much shinier and cleaner than the one in #502, and indeed it is. You have to consider that this picture was taken when the engine was new, 1984. The one in #502 has thousands of miles on it, and was not constructed for display. Therefore, it is logical to deduce that the two engines are not going to appear to be exactly the same.
