New Tyco Electronics / Amp-Duac 16-Position 2-Row Vertical Shrouded Headers, with Square Male Pins, Through Hole Solder Mount, Part Number 794429-1.  Each bid quantity is for a Lot of Ten (10) Pieces.  You may bid / buy any number of lots, up to the total quantity available above.

These were purchased at an electronics wholesale company liquidation earlier this year, and they were brand new in the original factory boxes.  We packaged them in heavy Ziplok bags for resale.

Mating connectors are readily available for the Amp-Duac Series, however, these are now considered 'obsolete' because they contain lead and therefore do not comply with RoHS requirements.  A bunch of people got together and decided we should throw billions of existing electronic parts directly into landfills - rather than putting them into appliances first, using them a while, and then throwing them into landfills.
