Prompted by seeing an enquiry in the wanted section, I have just checked whether my favourite high voltage axial capacitors were still available from CPC and found the range is reduced and the prices much higher than last time I looked:

Farnell still stock a few more values, all at higher prices:

They are still cheaper than the alternative Kemet A72 series at RS, though:
