What is the name of this beautiful red head model from the mid 70's?

This is a earlier novel by author John Colleton titled, "Replenishing Jennifer." Like most of his books, the publisher used the same image on the front and back covers. The earlier novels, of which this is one, had the models almost naked! This one was very sensuous as the model is barely covered by only lace and even at that, part of her left nipple is exposed. I always thought these books were so hot!
