Well, there is a lot more of it than I thought, the guy listed dimensions very strangely. If he takes my offer, it will be worth the effort for sure, if not it didn't cost anything to make an offer.
There is enough of it so that I could use it in the quonset hut too, I think it would be great to setup under a mezzanine. At some point someone suggested this exact stuff, it is just really expensive to buy, it is a "spacesaver filing system". Basically the shelves can be rolled tight against each other and then you open only the one you want to access, so it essentially eliminates all the aisle space except one aisle. This picture is not the actual stuff, but it is similar. The sellers images are kind of crappy, so this is more representative.
