So I pulled the boxes out. These two are completely different from the ferrite core memory modules I have. I have some hand wound modules from Spectra 70, Fabri-Tek, Core Memories LTD, and Data-RAM. In these pictures, the top one has no ferrite. This are just woven wires. The bottom one might be woven, but it is completely solid on top of a copper sheet. It would break if I gave enough force to bend it. The bottom one I haven't seen anything like it.
