I posted the same question a few weeks ago! We own a 1973 Compact Junior that came with no fabric thing for the pop-up. What do you call that part anyways? Here is the link to my post: http://www.fiberglassrv.com/board/read.php?TID=3501
I also contacted the RV/Motor Home heritage center
which has a library of old manuals, etc, but they had no info on these trailers. It appears that the company went out of business years ago.
SO...I am making one. I bought a rubber coated tent flooring fabric, screening and plastic for windows
, and lots of velcro...and I'm now in the middle of a big sewing project in our garage. Materials came to about $100. I think it will look pretty nice when it is done. I will try ot remember to post photos when it's up.
