I picked these up from my contact at CSI. Yes, they are custom caps 
(nothing even close on the their website). They were built for a 
customer and for one reason or another, CSI got stuck with them (been 
sitting on a shelf for a while). The contact at CSI (name escapes me as 
it's been over 10 years now), but he is the one that told me they were 
polystyrene. Because the company I worked for at the time bought 
hundreds hv pulse caps from CSI that they were pleased to throw me a 
bone. I talked about the application (they were well aware of Tesla 
coils) and he thought these would perform very well. I was extremely 
lucky (and extremely happy) to be given these caps.

Take care,
Bart
