#2. NLR Zebra, w/ or wo aventurine= most have av.
#3. NLR Rebel, w/ or w/o aventurine = most have av.
#4. Looks like an NLR Red Zebra, if so w/ or w/o av still a red zebra, sunset is a Rainbo, this one appears to have more of an NLR structure ??
(NOTE) NLR'S can come in a wide variety of patterns i.e. swirl, ying-yang, one seam, 2 seams, no seams, time is your best ally as it is mine.
