[Milsurplus] Unk circuit board from ?

[Hubert Miller]

When I was working in a genuine actual electronics surplus store about a half century ago, we had a sideline of cutting off the gold plated edge connectors on circuit boards.
The store had a large cutting device; I imagine it looked somewhat like a metal break, but had a big cutting blade instead. Sometimes we would get garbage cans full of 
circuit boards to process. I saved a few "processed" boards I thought were interesting. I don't know how lucrative that project turned out to be. I skeptically imagine that it
was about as rewarding as the Alaska Gold Rush, where most participants if they were lucky, earned most of their investment back.
