Just curious...can anyone id the system that used
these two types of core
memory? I am thinking the first is a hand-made custom core, but the 2nd is
definitely from a commercial system. Looks kind of IBM-ish but it's
nothing I can ID. It's not an IBM 1401 I don't think.

It's not a 1401 core plane. Here are a couple of pictures of what (I am pretty sure)
is a 1401 core plane that I have from my dad:

Close-up. Has a sharp molded corner and the grooves for the wires:
