Conductors in 'loom'? Maybe?
Years back, in an old structure that was an American Legion Hall & Offices, the second floor area was all K&T. The surface twist style switches had wooden molding with grooves routed for the conductors. I fondly remember hunting for a fuse box, only to have one of the senior members say 'sonny, it's located in the baseboard right here!' He was 100% right on, two circuits, four fuses block, custom 'box' lined with 1/2" asbestos (the real thing) board with the baseboard neatly mitered to hide it.
