A Palitoy grading is a good idea. Like I said before , the difference is so minute between blue/black and black visually I don't think any kids would have noticed at time, let alone checked them with a flash light. It hardly seems worth being an intentional difference.
Maybe one factory only had black dye available so used that and it ended up with the POTF Lukes and Han trench only, after all there are no new blue dye accessories for the last 17 but a few black ones.
