Natasha Anastasia Nude, looks SOO like Sian Blencowe!

I came across these pictures from Mayfair magazine a stalwart of the men's magazine scene in the 80s and 90s and can across these pictures of Natasha, who looks suspiciously like the Sulis Lingerie model Sian Blencowe. However, more investigation shows it is not, it is British glamour model Natasha Anastasia but gosh do they look similar!
