I went back and looked at some more pictures of the MK St. Mary's cat's-eyes and there are wavy vanes that show up so I'll "reverse" my comment and say they could be St. Mary's cat's-eyes.
I don't think it is Vacor Liberty. As mentioned, they did not have green in them. It fits all of the colors for MCS and, as we all know, there are a bunch of "screwed up" Pelts out there.
