Socket for Nixie Tubes Military Version IN-12A, IN-12B, IN-15A, IN-15B, IV-22, New 6 pcs

NOS Russian part. The silver is so tarnished you have to lightly sand the terminals to get a good solder connection. Also very tight fit for NOS American made IN12 such as the national 1979-0009 nixie tubes I have. I broke 4 tubes trying to seat them properly.
