Description

This Alternating AC/DC Ammeter sits on a large wooden box, with Bakelite? mesh-grid sides and holes in the wooden top surface. There are 4 rubber feet. There are 5 screws - 1 of which is capped with a bolt - these sit on metal rectangles. The ammeter is in house in a smaller hinged box, with a glass faced dial, reading '0-50' on the scale. The lid has a paper information page, with blue print and handwritten notes on it. The lid is kept closed with a metal catch.
