The HTR and RES pins were both a little bent. Luckily the vent port wasn't bent or the D2 magic could have leaked out. The device is heavy so I think people picking it up would end up pressing against the pins causing them to bend.

A crack in any of the ceramic-metal seals would impair the hermeticity.

That's good point. I was thinking along the lines of the vent tube being punctured/cracked.
The 'pins' you see are more of a terminal block that fit over the actual pin and have a set screw to attach to the pin. I'll remove it tonight and do a closer inspection.

The thyratron had a little ceramic chipped away by the pins but it doesn't look deep enough to be a problem.

I got this Xray transformer earlier in the year off of Craigslist. The dentist even gave it to me for free when I told her it was for my electronics hobby.
I don't see any voltage/current specs. Does anyone have an educated guess in what they might be?

The inside of the spark gap transformer only had a transformer in it. It was already drained of oil.
I suppose the instructions on the case were for whatever system/unit it was part of.
