[Amps] Query about capacitor value

Back about 20 years ago Peter Dahl was selling those NWL 53 uF 5KVDC oil  
filter capacitors for large $$. I purchased two of them for 4kv power 
supplies  to use with 8877 amplifiers.
 
Both capacitors exploded after several hundred hours of operation with oil  
spray all over the insides of the power supply. Since then, I have used 
strings  of electrolytics without any problems.
 
Lesson learned. In my opinion the value of one is zero.

I'd like  some advice on the value of a high-voltage power supply capacitor,
which I  plan to offer for sale.
I have a 53uf, 5kv, oil-filled cap (no PCB's) sold  (manufactured?) by NWL
Capacitors carrying their part number 10208. I have  looked at their web 
site
but the cap is not listed but comparable parts in  their product line are
surprisingly expensive!

Any input would be  appreciated.
