LDW, I think that the model you posted above as "Claudia" is a 1970s model and part-time actress known as both Lucienne Camille and Sylvia Bayo, whom I knew briefly. She was, I think, originally from France. She died in 2006. She was a very charming and kind person. I doubt there are any pictures of her that show her lower back; when she was very young she worked for a very nasty pimp who settled labor-management disputes with a coat hanger and left some scars on her. She was very sensitive about them.
Hmm - I am not sure - while it could be Sylvia Bayo, I don't think that it is.
While Sylvia had amazing breasts and
huge nipples I don't think that she was quite as big as the girl posted by LDW although it is hard to be sure.
Another consideration is simply the quality of the image - all of the images of Sylvia that I have ever seen are scans of magazine images from 30 years ago and it shows - that picture just looks much newer.
Anyway, for comparison, here is a shot of Sylvia ...
