The Hiker's Bible by Robert Elman 1974
This great book by Robert Elman contains a few different lists for different occasions. Lots for 'him and her' and 'how to divide up equipment.' The most concise and relevant for here is one Elman has sourced from a Sears Hillary catalogue for "longer backpacking trips."
“Pack and frame 4 lbs. Down sleeping bag 4 lbs. Nylon tent 7 lbs. 8oz . Canteen 1 lb. Stuff bag 6 oz. Short foam pad 1 lb. 4 oz. 1 compass 4 oz. Knife 8 oz. Flashlight 8 oz. Nylon cord (40’) 6 oz. Maps 6 oz. First-aid kit 6 oz. Cooking grill 1 lb. 8 oz. Mess kit 1 lb. 3 oz. Fork-and-spoon kit 6 oz. Can opener 1 oz. Dishcloth 2 oz. Plastic bags 2 oz. Nylon poncho 1 lb. Extra set of underwear 12 oz. 2 extra pairs of lightweight socks 4 oz. 2 extra pairs of heavy socks 8 oz. Toilet kit (including towel, soap shaving equipment, insect repellent, mirror, toilet tissue, etc) 1 lb. 12 oz.
Total weight 28 lb. 2 oz.
If you were to add a one-pound trail ax, a stove weighing about 1¼ pounds, a nylon tent fly, a set of thermal underwear, a jacket and even a pair of walking shorts, the burden would still only come to 35 pounds, and eight pounds of food would bring it to 43. That’s going reasonably light without roughing it.”
Nice list, although I'm not sure 43 pounds would still be classed as "reasonably light."
