Model name I have seen quoted as Lisa McBride?

'She was so well known that it should have been impossible to disappear' - out of a naturist scenario she would look like any other person in any street in any town...dressed I doubt even in the day anyone would know her or notice her even if they did know her naturist pictures...

Margaret Wallace - Blue Climax No. 16 August 1980 apparently - vintage-erotica-forum.com/t5273-p3-mar...

I have a thought that this may be in a Riva Speedboat or similar
