At this point I know the gallery was called "Chrome-bars" by Ron Harris, and dated August, 2004. I don't yet know who the models were in that photoshoot.
Yes! I still don't know who this girl is. The Harris-Archives site is defunct. I'm trying to sign up for ronharris.com, but they don't accept Visa cards?
But one of the babes featured in that set is Sara St. James according to one forum I looked at.
She's not the one you are looking for but it might lead you down the right path.
And I found something to suggest the person you are looking for was simply referred to as "Contortionist" in another gallery but I'm not sure if it was her or not.
