I'm no expert on this but IIRC the flexible metal tubing leading to the juction box was known as Greenfield conduit. It was used in houshold electrical wireing as early as 1926 that i am aware of. I believe the knob and tube household wireing was used or discontinued very early around turn of the centrury and involved using bare wire with no insulation. I have a few of those porcelen or baked clay or what ever they are made of tubes around here. They're white and used now for touching up knife blades.
