Original poster: "Mccauley, Daniel H" <daniel.h.mccauley-at-lmco-dot-com> I responded to the one individual asking about Philadelphia area coilers, however my message got bounced back. Anyways, I live in Philadelphia and have a number of coils to demonstrate if you are interested. Contact me offlist at dhmccauley-at-easternvoltageresearch-dot-com Thanks Dan
