Oh boy the fun and remembrances in reading through the threads! Some pieces I still use, occasionally...
North Face down jacket, circa 1975, polar model. This down jacket has more patches and duct-tape then the original rip stop fabric! Still in-service for winter forays and cold weather expeditions. North Face has replaced the zipper twice and re-downed the jacket once.
Kelty Ruck Sac, circa 1974. The original 'go lite' pack, with ski slots, leather bottom, metal expansion zipper, metal pocket zippers, and a clip waist belt. Retired now yet, still functional.
Svea 123 stove. Missing the tune key. This stove has served me well throughout the 70's-80's. Can't toss it out...you never know!
