I think it is from the 1970s. I brought it home last Thursday. It is very heavy and commercial grade. It is 8 feet long and should start from a 66 inch tall welded pipe ladder. It will replace the ghetto stripper pole and the little tykes slide that my playground used to have. The little tykes slide broke and was cracking a lot from me since I was over 4 and a half time the weight limit of the plastic slide.
