I used to have a whole set of photos on my web site of the inside of the 5071A Cs tube, taken during a tour of the Santa Clara production facility. Sadly, I was asked to take the page down. But Skip is ok because his photos are of a Cs tube one or two generations older. Thanks for posting those.

Your photos are a welcome alternative to these:

Although. you have to admit the first one has a certain charm.

Here's the inside of the original cesium bean tube:
