[Collins] Need help with connector

[PRH at aol.com]

Thanks for the many people who replied both on/off list. I have taken a  
magifier and a strong light and get the following nomenclature:
 
Bendix
12S-3P
-8531
MS3102R-
 
Now, can anyone help me locate one of the mating connectors ( preferably  
without spending an arm and a leg)?  My other alternative is to remove it  and 
deal with a bunch of unwanted holes!
 
Thanks agn to all......
