Leeds & Northrup 8686 Millivolt Potentiometer w/ Original instructions

Description

This sale is for a vintage Leeds and Northrup #8686 Potentiometer. Looks great, battery compartments are clean and comes with original instructions. If I were a betting man this item still will do what it was tasked to do. However it has not been tested. So it is being sold AS IS. Thanks! WE ARE THE MUDLARKS. We keep diggin' so you don't have too!!!
