Hi, you currently have the Portia Prinz series that was printed by Eclipse Comics in 1986, but not the series done 10 years earlier.
Not sure if you want to make them Vol. 1 & Vol.2, or just put the Publisher names on the 2 different series, but here is info on the 1st series for this character:
Publisher: Desperado-Eastern

Stories and art by Richard Howell.
#1 - Winter 1976
#2 - Spring 1977
#3 - Winter 1977
#4 - Spring 1978
#5 - Winter 1978
