Yup, that's a crazy price.  Maybe if it was rated for 100kV...

This is not a time-limited real auction. I take the " buy it now " to mean that he could not sell it by auction so is looking for a buyer willing to pay an outrageous amount for this item.

That item is almost certainly a trigger device. Looks like an SCR or something, marked 12V on the end with small coils in the clear plastic underneath is. Those caps can start your heart, but they can also stop it! It probably has an internal resistor or one across the terminals to discharge it when not in use. The ones in microwave ovens have had them for some time.

I suspect I can't really add anything but I have taken a few medical HV bits apart before and that kilovac looks to me like a high voltage relay / trigger tube and the transformer looks like a pulse transformer, usually for adding a spike of voltage to a pedestal / stored charge by being wired in series with a circuit. This spike usually then causes the stored charge to flow by forming an arc or triggering a tube...

Ahh, I mixed you up with another member here who has had them for far 
longer, you only commented in this thread: 
https://groups.io/g/neonixie-l/topic/prototype_multisegment_tubes/1048709?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,0,60,1048709

It would be really nice to see them glow!
