older roof installation supplies (Hurley (loop road off of 209))

I have four of what I believe are called "jack stands" -- the big complicated looking things sitting on the floor in the picture. 28 of what I think are called "roof jacks" -- the triangle sort of things hanging on the wall in the picture, and a handful of roughly yard long metal rod sort of things bent on each end which I'm pretty sure went with the roofing supplies. -- kinda hard to see in the pictures hanging next to the ladder bracket.
