Don't quote me, Aluminum wiring was in the late 60s to very early 70s. Cloth Braid wiring has a long history, and mostly was taken over by TW in the late 50s early 60s. NM cable without an EGC was actually produced in the late 30s or early 40s. If you were to go to Google, type in the history of wire installations and you can find some good stuff.
