Thanks for the responses. I’ve sent out a note to Jack.

I have a buzz coil. Not a ‘T’ coil, but it easily fires the plug. I plan on making an oak box to contain it and a battery. Wiring’s all ready to go.

This has been a 5 year project. Most of the time spent scrounging parts. Absolutely not because I have ‘way too many projects and a short attention span (ooh look, something shiny)…
