I'd like to offer up an opinion, if I may. I have had MKs in the past where the black veneer was very anemic and gave off an almost purple hue as a result. Since the questionable purplish stripe has darker edges, it seems to me that it leans towards black as it's less anemic in that area of the pattern. Plus, the darker lines follow into the green in some parts. Could this just be an anemic MK? I'm just trying to jog my memory from when I did this stuff a lot more several years back. Thanks for humoring me.
