“Funny, my Dads old Kelty external frame had load lifters to account for the non adjustable frame. Of course, that was in 1964. When did internal frame packs hit the market?”

All the brochure pictures were from the early 60’s — probably 1963. I grew up with Kelty packs and don’t remember any kind of load lifters available from Kelty or the after market. And there were several companies that made add-on stuff for Kelty packs, especially A16. But it is possible someone added load lifters.
The Trailwise external packs had what looked like load lifters, these were adjustable shoulder straps that attached to cross frame. This was the only attachment for the top of the straps.
Early Coleman Peak 1 packs with the plastic frames DID have load lifters. Probably late 70’s or early 80’s.
In case Ike pops up with his Aarn stuff, he might want to check out Bal-Paks from the late 70’s or early 80’s.
Supposedly Greg Lowe made the first internal pack in 1967. I didn’t pay much attention to internal packs in the early days, but don’t remember load lifters until Gregory released the Cassin in the late 70’s or early 80’s. Internals were mostly used by alpine climbers and not very popular until 1984 when Colin Fletcher released the Complete Walker III. Fletcher made internals popular. My 80’s vintage Mountain Smith Frostfire internal had lifters.
