When I worked in the foundry (early 60s) we used Kirksite in place of wooden patterns because the pattern would last longer. It did not have the shrinkage that normal metals experience when cooling from a molten state. I inquired as to its origins and was told it was invented by a fellow named Kirk during WWII. I made a pair of loco sideframes out of it and still have them.
If Packard was using Kirksite for a die material and it wasn't invented till 1965 then they were probably using it on that V12 they were making.
