Can someone identify this component for me? Apparently I've got dozens of them.

Looks like a 0.33uF/250V capacitor.

Yes.

The "K" is 10% tolerance, "J" would be 5%. It is a plastic film capacitor that has no polarity. 250V capacitors were used a long time ago with vacuum toobs.

But they did not look like anything like this, and usually had paper dielectric. 250V rating has not anything to do with tubes and is still used for a hell a lot of things.
