I bought a Kelty full length Mountaineer Pack in 1958 to use as a camp counselor leading backpacking trips. Paid $30, $5 more than the Standard Pack. It was shipped from Dick Kelty's garage.
Kept the pack until last year when I got rid of my 300+ Mt Book Collection, alot of camping/hiking stuff, and in the process, donated the pack back to the Kelty family as it was evidently one of the oldest ones around. The only thing I changed was to replace the original waist belt with an up to date padded one and I added a large zipper pocket directly to the upper back part of the pack. I once entered a contest for best backpack and got aced out of lst and 2nd by packs with alot of patches, memorabilia, but got the $10 3rd place award probably since it was the oldest pack in the contest.
