Replace "obvious cutlines" with "obvious pattern". I dwelt too much on lines. It's broader than that.
MFC's have the 9 and tail.
CAC's often have obvious seams, one or two, sometimes with a "road and tunnel" pattern. In your first pic, I thought I might be seeing the "tunnel", but without the seam and road underneath it, it's just a fold.
Peltiers can have their famous feathering.
Akros CAN have a pattern -- sometimes they were handgathered. But they also are known for a more random look with their non-handgathered examples. So if the famous patterns are lacking ... that points to Akro.
