Wow, that thing is absolutly beautiful! IS the powder held in place with 
cardboard???!!!!! I love the Gap, I hope I find a similar one in the small 
arrestor (the Big one I'm thinking will have a single gap, I don't know why, 
just a hunch). Where did you find that? It looks like from about '40 or so, 
am I right?

Thanks for the education! btw, can you email me off list? You have a lot of 
experiance in Quarter shrinking and the truck just dropped of 1200+lbs of 
capacitors here (250 of them, for the Thumper project) I have a couple 
questions for you. :)

thanks
