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.
