You are bidding on 2 matching Sun meters that were made in the mid 1940s.  I got them loose, so I do not know what they came from.  The ammeter shows good continuity, but the voltmeter does not.  They are attractive meters, but need a better cleaning.  They are fan shaped and measure 3 3/8 by 4 1/2  inches at the front, and 2 3/4 inches in diameter at the back.  They are about 1 inch deep behind the panel, not counting the terminals.  They should be useful for someone.  Shipping weight is 1.25 pounds.  Please see my other auctions for more interesting radio and audio items, and tubes.
