Old school antique slide. They don’t make them this high anymore. It is taken apart currently, and these are the best pictures I could find of it upright.
Made commercial, stainless steel, galvanized piping and the steps are cast aluminum. These were put I playgrounds at school back in the day. Made so strong!
It could probably use some fresh paint, a wash and a buff but works great.
Pick up in Pittsfield New Hampshire and must have a trailer and help.
