I'm somewhat surpirsed it isn't on parachutemanuals.com or another electronic reference I have but...
I do have a hard copy and could supply a copy if you can't get it electronically.
Don't think it was on the market long. It was pre Swift Plus. 210 sq. ft., 7 cell, Lissaman 7808 airfoil (same as most of the the early paraflite products), aspect ratio 1:2.23, pack volume 440 cu in per paraflite. I think any Orion would be at least 19 or 20 years old.
I've packed one once or twice but not since the mid 90's.
