Most of the time, reality makes me feel pretty old, because I am. But when I read threads like this, I feel so young! Unfortunately, I have not digitized most of my old 35mm slides. Maybe I'll dig into that this coming winter. My oldest climbing pack was a Himalayan from the early 70s, probably something like 15 liters. I don't know if it's still in the archive.
Thanks for putting this thread up. Feeling pretty chipper among all you old timers.
We loved 'em, Jim, because they had no exterior pockets (to snag if it needed hauling), a single leather strap with a metal buckle to secure the top flap (easy, quick access), and accommodated two liters of water, lunch/munch food and rain gear, had a heavy-duty metal ring for hanging at belays, and they were rugged (canvas-like cotton material) - never had to open the haulbag during the day - only during bivouacs.
