capacitor question

[Tesla729-at-cs-dot-com (by way of Terry Fritz <twftesla-at-uswest-dot-net>)]

Hi Fellow Coilers,

I have a couple of large capacitors that I was hoping someone
might be able to tell me a little more about, as far as Tesla com-
padability goes. They are phenolic cylinders with dimensions of 
16 1/2" x 6 1/2" in diameter and the terminals on ea end stick
out another inch (18 1/2" total length).They weigh about 23 lbs ea.
The print on the side reads:
    
     0.075 MFD  80 KVDC WRKG
     TYPE 2701
     WEGO CONDENSER CO LTD
     MADE IN ENGLAND

I was told that these were X-ray capacitors. If anyone can tell me
anymore about these, I would greatly appreciate it. 

Thanks, 
David R.
