I recalled that Tina Hudson had a role in the James Bond film "Octopussy". She played "Bianca", who assisted Bond while on a mission in Cuba. Bianca served as the 'eye candy' to distract Bond's captors long enough for him to make good his escape.
So I checked IMDB.com, and James Bond Multimedia.com but neither listed "Tina Hudson" as a pseudonym for "Martina Jendretzke". HOWEVER, IMDB does list that Tina Hudson did appear in Playboy West Germany July 1983, Issue 7, on pages 54-59, in a pictorial by Siwer Ohlsen.
