Those are called 'doorknob' caps, typically rated around 20 KV. Used for filtering HV in electromagnetic-deflection sets. You'd probably want to replace them for aestheics. If they're good, they might come in handy in future project(s).

They are also used in some electrostatic sets IIRC the Hallicrafters and or National brand sets.

If the value is right they could potentially be left in. These capacitors are fairly reliable but once in a while, you will find one shorted. I always look upon them with suspicious optimism.
