The 80s PE-175 had a weird headstock top border line as well - very distinctive, with little "ears" on the corners. The other PE-180, PE-190, and followup offerings from those lines had the switch on the upper portion of the treble bout. The FA-175 Herb Ellis Model did not have a marble-ized pickup guard like this one does - that did not come until the 90s, and was on the FA70 not the PE-175 (where the PG was black, or very, very dark brown, or very, very dark tortoiseshell). The later FA71 did not have the same slope downward from the neck.
In the early 90s (I am not sure when it was introduced) there was the FA70 which had the same format as this guitar.
Note the PE-175 of that era had a different headstock upper border outline. In the early-mid 80s, the only Aria Pro II shape like this (where the bass bout slopes slightly downward from the neck joint, the upper portion of the upper bout has a kind of small 'angled' feeling, and the switch is on the upper bout) was on the PE-175 Herb Ellis model. My best guess (which is worth perhaps the paper you have printed this on (yep, that paper)) is that you have identified this correctly.
