There! Pickled. At least enough to do a pressure test; there's still some scale in there, though.

The scabs on the outside are not pits; they're raised blobs that I think are what's left of the old insulating material. Anyway, I can scrape them off.

First inspection looks good. It holds water at atmospheric pressure, and that's a great start. No leaks from valves, either. The silver solder is smooth and uniform-looking, and I anticipate no problems here.

So, off to make some plugs, find a gauge, and pump it full of water (BTW, the wooden crate this came in had a little feed pump in there, too. Bonus!)
