A lot of my older stock is pretty much the same as yours as I have some capacitors which may be as your first, but not in packets, so I don't know details. I do have a number of Erie ones like your second, which I find useful and reliable but I have not tried them at high voltage. Interestingly I did come across some others I have - 330pf but slightly smaller in diameter than your Erie ones, which have 5kV rating printed on them. They are fatter than most.
