Fantastic! Apparently the mate-n-lok connectors were bought out a couple of times and there are different market offerings. This one seems to be "commercial" , not what I had seen.
I got a clue from Charlie Hammes, and was just researching Mouser.
Thanks to all. Hopefully this will help others if they can find the thread.
