Here's a nice exhibit:
The ones I used were ceramic, but black/gray not white. No lids,
gold leads. Typical of these was the 723 JK flip-flop--probably
because of defense spending, easier to get and cheaper than the
plastic DIP or TO-99 package, if you could find them.
The original flatpacks, I believe, came from TI. DIPs came later.
