You are bidding on a Western Electric Type 194B condenser/capacitor from the mid 1930s.  It is dual, rated at .2 and .5 MFD, probably at 500 VDC.  It is good, testing at 2.53 and .58 MFD with my Fluke meter, no high voltage applied.  It is in fairly nice condition, but some silver paint flaked off in cleaning it.  The date code is 1-37.  In size, it measures roughly 1 1/2 inches by 1 inch in cross section, and is 4 3/8 inches tall, not counting the terminals.  It should put to use.  Shipping weight is 12 ounces.  No shipping to China.  Please see my other auctions for more interesting radio and audio items, and tubes.
