I found the datasheet.  It's clear enough for my purposes.  The part 
numbers are 582388-9 for 22-pins and 582372-9 for 14-pins.  Card fingers 
on a .156" pitch seem common enough.  The problem then becomes the fact 
the socket is mounted to a metal panel.  There aren't many card sockets 
like that around anymore.  The price break at DigiKey is 1000 units. 
Interestingly, they do have the metal inserts in stock.
