I don't have any pics unfortunately, but when I briefly worked for a fire alarm/extinguisher company I had a tank re-valved. It was dead easy. Just let the pressure off, unscrew the old valve, clean thoroughly, and put the new valve in. They had the hydrostatic testing chamber, so it could be re-certified. I sold it on to a friend a few years later. Before I got interested in teardrops.
