Am pretty sure that the two Whitehouse magazine thread links lead to pictures of our girl. Here she is given the name "Gwen".

Admittedly, you only see her face in one picture of the second link, but I do note the model has the same rings on her fingers and/or "intimate anatomy".
PS I will always fondly remember her as "Lynda from Whitehouse". Shame we cannot get a definitive confirmation of just one, "true" name for her. If only we could put some creedance on her statement in the "Mary Millington's Worldwide Striptease Extravaganza" where she says she is Katrina from New Zealand? This is more likely to be a character name for the film than her real name? Certainly does not seem to have a relevant accent!
