US Navy Leeds & Northrup Potentiometer & Galvanometer. Serial# 633650. This is
an absolute beauty!!! Oak cabinet and instrument in excellent original
condition. The Bakelite top is very clean. The knobs turn well. There is a
large horse shoe magnet in the left compartment. Cabinet is 20.5" x 9" x 9".
The unit is fairly heavy. The case has two rubber foot pads missing, plus the
original leather handle. Those are easy fixes for you. This will make a nice
display for classroom, home school, or office. Great looking antique.
