This topic forced me to search for and locate my large size Kelty pack, circa late 1960's. I purchased the pack at the Kelty store in Glendale, California. I did update the waist belt with what was then a "better" Kelty waist belt; my guess is I updated the waist belt in the early 1970's. Not only do I have my original Kelty pack, I still have my Svea 123 stove and Sigg Tourister cook set. The Svea 123 nests in the bottom of the Sigg cook set.
During my search, I found a box with the original Kelty and Svea 123 instruction sheets, some 1970 Kelty store receipts, etc.
I have backpacked, mainly in the Sierras, for too many decades to contemplate, with the usual gaps for young children at home, work demands, etc. Over the past five to ten years, I lightened my gear list considerably. It is highly doubtful I will use my vintage gear again. So, if anyone is interested in my "vintage" gear, send me a PM to start the process with photos, etc. Although looking at my “vintage” gear brings back wonderful memories, I would be pleased if another backpacking enthusiast could enjoy the gear as much as I did.
If you want to look the gear in person, let me know. I live in Pasadena, California.
