You are bidding on 2 Western Electric thermocouples, Types 22N, and 22AM.  They are in nice condition with black bakelite cases.  They have 4 pins in typical fashion of a four pin tube with side mounting pin.  The pins have low grade gold for positive electrical contact.  I think the value of the gold is more than my asking price.   They test good.  In size, they measure roughly 1 3/8 inches in diameter, and are 3 inches tall, not counting the pins.  They should be useful for someone.  Shipping weight is 8 ounces.  Please see my other auctions for more interesting radio and audio items, and tubes.
