wccdusa still lists core and coil type nst's. They are not forgiving 
to abuse as the France units are. I burned out 2 of them while 
noticing that it was putting out a spark about the same length as the 
10/23 obit, though it was just a 5/25. Still, they can be 
disassembled, and one of these days, just for fun, I intend to wind 
my own secondary with 30 gauge wire, and see what kind of output I get.
