Jonathan, those are the side screens that were offered on  ASI Rivieras and then passed onto Country Homes camper models
they are no longer produced and are a great screen, offering excellent ventillation and are secured with 4 small ss. screws. 
pets don't favor them as they can't stick their heads out the windows while driving, but also keeps small hands and pets inside/outside.

I have a set on my 1980 ASI and love them, I'd prefer to have Jalousie windows from an early bay in my van but haven't committed myself to that modification yet.
you could ask the auction holder if they'd ship the screen frames only and that should save some $$ over the $30 shipping fee they're charging.

I tried already unsuccessfully to communicate with them, so better luck to you.
