I found a photo of a 10th Mountain Division soldier wearing a rucksack with the wire frame. I also discovered the frame can be removed and exchanged so worst case I can get another frame. Looked it over again and it's in decent shape with only one issue, the end of the one strap has been cut off losing the metal tip and about an inch of fabric. Fully functional. Very minor, there are a couple of loose threads in a seam or two. No holes, no tears, leather straps are good. Opted to take a chance on it.
