Hmm…
According to the Kelty Heritage Timeline page:
1973: “Full-feature” packs
Kelty introduces the Tioga and Serac packs, the first new designs since the early 1950’s.The new packs feature a fully padded, one-piece waistbelt, larger-capacity bag, covered zippers, waterproof fabric, and a new cam-lock buckle. The Serac features a covered sleeping bag compartment. Additional daypacks are also added to the line.
That said, they don’t seem to be waterproof at all – only the panel of fabric that lies against the frame is coated on the inside (consistent between all three packbags I have).
Both my XL Serac with rock-hard suspension padding and newer logo, as well as the latest acquisition with the older logo, have all-metal cam locks – I’ve only seen the version with plastic in your photo (shown below)…I assume you are certain that yours came with the pack new? Because the padding is in such perfect condition on the one I have, I thought maybe it was a replacement suspension, however the stitching is identical to the rock-hard one, and I thought that any replacements Kelty sold were of a newer style…


Note that on the older packbag with black leather, there are only 2 notches in the leather patches on the sleeping bag compartment rather than the usual 4:

I wonder if this is an early prototype made in ’72, then the Serac production got put on hold when the CML acquisition happened? I guess we’ll never know; I wish I were around back then!
