What is the name of this vintage/retro porn actress?

And as you might have already anticipated; I'm also very curious as to the name of the film/video the GIF is from. I know this is going to be a difficult one to identify because of its age. But any help—even in the form of guesses—will be greatly appreciated! This beautiful lady, and this short GIF, have haunted my fantasies for a long time. I know I've seen her before, but I just can't seem to get a grip on her name.
