Any UNC alums, there is a pair of Ben Silver blazer buttons on ebay for a great BIN price. It's a great find, let me know if anyone picks these up.
Benson and Glegg might be one. It looks like they might be Silver's supplier for both buttons and cufflinks.My friend
That is cheap. Very nice buttons. There are 2 other button suppliers that are more reasonable in price as well.. Name blanking, but can search here for them.
