This internal frame pack came to me second (possibly third) hand with the straps all in a mess. The yoke attaches with two straps on the bottom and one on top.
It’s obvious that the top strap is threaded through a buckle located between the load stabilizers and the bottom straps thread through a series of reinforced straps. I’m just not sure how this is to be done without a turnbuckle digging into your back.
On a possibly related note, the aluminium stays have the ability to slip out the bottom of their sleeves when the backpack is not under load.
The lower shoulder straps connect to the D ring riveted to the stays. Is there another strap that connects to this ring and holds the stays in tightly?
I’ve looked for a tag listing the model of the pack but haven’t found one. My guess is that it’s over twenty years old.
Does anyone know how to properly configure this bag?

One of two identical mystery straps. All the straps are the same width so they could go anywhere.
