Not my collection, the vault. I encase it in lead to shield it from the radiation of the nuclear waste stored across the river at Hanford, WA .

My brother had occasion to visit the Hanford faciity about 15 years ago proposing to establish the project plans to eventually get rid of all the waste from WW2 uranium processing. He said it was such a mess with almost no records that he didn't want to get involved with it at all.

I protect my own health with a tin foil hat.
