ok thx PH now maybe we can get some where. yes these are the wide multi (many) finger cinnectors. they came from the air force base a few years ago, what Im tryintg to find out is, on some of them the case inclosing the pins the actual connector is like no metal I have ever seen. no spark non magnetic and as hard as a drill bit. it is semi shiney (shiney but not mirror finish) and un like other connectors it has screws holding it tigether
