No broken ropes just poorly placed stakes, and maybe some hooliganisum.
Definatly, just one pole, no ridge line, did have a line or two at the back to keep the tent off your feet, sorta. Ropes were natural fiber. Tent was of light canvas, might still have weighed over ten pounds. Only place you could sit up was right next to the pole, a three or four section aluminum job, do remember they would store inside each other if not bent up. These had some use on them when I first saw them in 1971, could be as old as 1965.
After using my Clip Flashlight by SD I would not want to go back except for nistalga reasons.
