Ah, what a tangled web we weave! It sure would be nice to have a time travel device or someone in the Hasbro shops who kept immacculate notes as to calibration settings, mold numbers, carvers, artists, stencil cutters, hair types, glues, plastic mixtures, dye batches, paint ingredients, color gradients, reground percentage of plastic used, acceptable variation in all factors...the color of the book-keeper's eyes...but, unfortunately, the 80's were also full of deviations and inaccuracies that just don't much exist now that the human error factor has pretty much been wiped out and replaced with computers and robots.
