Scintilla is long gone since most of there product designs were bought out by Bendix back when Christ was a corporal. The Vertex magneto is about the only Scintilla item being used to any extent now days but it wasn't an aircraft mag so it went its separate ways after the patents ran out. Bendix ignition systems was bought out by Teledyne Continental Motors way back there too. The only small mags in wide service from TCM/Bendix are the 200 and 1200 series for 4, 6, & 8 cylinder aircraft engines. I don't know if any of the points sets used in them are even close to what might be needed. Their points sets and condensers are the best quality out there for obvious reasons but aviation people have to pay dearly for that quality.
