Thanks a lot for all your effort!
We now have:
Pattie O'Dora - Men Only 51-06 (1986)
Mattie Kay - Gallery GND Nov 1981
Mattie Kaey - contact sheets (typo?)
Mattie Kay W. - Girl Next Door of the Year Winners Jan. 1984 (winner of 1982)
Mattie Kay - Gallery August 1984
Mattie Kay Wolter - San Bernardino Sun November 27 1981
It seems we have a solve here.
MKW seems to be her real name, so I would prefer Mattie Kay as she used it in at least two mags and at the Gallery website.
