X-ray trans circuitry question

Last weekend's trip to the junkyard yielded the following large piece of iron:
http://seras.math.uiuc.edu/~cjschult/tmp/tmp.html

  It's rated output is 60kv, 3.5kVA.  I hope to use it as a Marx bank power 
source.  I've never dealt with one of these beasts before.  As far as I can 
tell, the hv tranny is supplied with conditioned 220V from the gold 
transformer (at the leads in the foreground of the center picture).  The 
outer winding on the large core is connected via heavily insulated leads to 
the resistor network.  Five additional inputs enter the picture here, two 
attached to the resistors, three go into one winding on the smaller core.
  The resistor bank is attached to a hv capacitor and the short winding on 
the small core.  The short winding has two outputs hanging loose, which I 
assume are the final hv output.  I'm also assuming the resistors, 
capacitor, the second core and windings are current limiting circuitry.
  I ask for help understanding the circuitry in the transformer.  The 
resistor bank, for example, has some  'mystery' devices on it that I've 
never seen the counterpart to: a yellow plastic 'black box' with two leads, 
a couple of sealed glass tubes that resemble blown fuses or spark gaps?
I will post a crude schematic once I figure some more out.

thanks,
Ben Ziegler
