Here is the URL for an article for spark gap modeling.
http://www.intusoft-dot-com/Newsletters.htm
Get Sept. 1997 NL50.PDF. It is fairly large so here is just the model. I
have been planning to try it but haven't yet. Good luck.

     One this note, does anyone have a SPICE model of a spark gap that they
     could share?
