Hey guys - saw this "Paramount" for sale on eBay this AM, and I was wondering what you thought.

Schwinn Paramount P 13 1979 Never Ridden Original Campagnolo Nervex Lugs | eBay

I emailed the seller, and the serial number is 20648, which doesn't match the normal Paramount numbering system. That (and a bunch of other stuff that just looks wrong) leads me to think that it's an early 80s Superior that someone has stuck a Paramount headbadge and decals on, but I might be mistaken. Any thoughts?
