Item number: 190372867210

I was watching a couple new old stock 531 sets a couple weeks ago that went for only a tad over $100.

What the deal with this particular set? It is the fact that it includes the original technical papers that makes is particularly special? Or just a couple bidders willing to go all-out to have it?
