Sometimes called a quack box because with today's medical knowledge we know that many of these things manufactured in the early days of electrical technology were ineffective.

This unit is labeled Amos M. Cato of Little Rock Arkansas.

I have never tried this unit and I recommend that you do not either. Has a tesla coil a gas filled lamp neon argon krypton a cautery tool and a bulb that looks like a christmas tree light but has a lens in it so it is a nice focused beam. I have not tried to clean up this box any because I don't know how to do that without ruining the fabric. Really a neat conversation piece.
