the most reliable information states that the part 3 and 4 masks (made during part 3) were clear acrylic, pulled thin, part 6 was also clear acrylic, part 5 MAY have been ABS, part 7 was likely ABS, dunno about latter ones personally. From what I hear acrylic is hell to work with, most mask makers use vyvak as a substitute, its still a pain to work with compared to ABS.
