Comparing currently-unlisted titles [both 'works in progress'], the
DBM alias for Gabriella Zaros must be Jennifer Dew.

DBM [or a DBM sub-label], dir. Basil Sandford.
My Italian version, as 'Fino all'ultima Gioccia', is short at under
70 minutes and may well have been cut.

That said, the aliases at least are [now!] unequivocal:
Lisa Gaston, as Livia Como- DAP;
Georgina Herminez, as Vicki Major- les-only;
Gabriella Zaros, as Jennifer Dew- les-only, 1/2-fisted by GH;
Susi [7], as Viola Vision- bbg, anal;
Elena Maria Ricci, as Jodie Marengo- bbg;
Ariel Bader- anal.
