Is that a glass tube with a visable "spark" gap? If so, it's spark tester, for ignition systems.

I can see this in use on a flathead engine.  Long spike grounds to the head, short one pierces the spark plug boot.   Used to be a lot of problems with high resistance plug wires, a problem that has gone away.

And testing the resistance in the plug wires used to be a standard step in doing a tuneup - back in the days of points and condensers.

 :tongue:  Back in the day (before i had a timing light and dwell meter), i used to just tune up my '64 Mustang by replacing parts and then listening as i made adjustments.   Somehow i don't think that would work now.
