Mike: (Trumpy); mamils snuck in above
Panelboards like the one in the pics are not 'common'...but there are still some around. Probably from the 1940-1950 eras.
Not 'home made'; this area was Federal Pacific, Westinghouse, Colton (local), Gavin-Graham,and a few other 'local' panelboard mfgs.

As I mentioned above, the 'heating' problems usually are from bad tension connections at the fuseholder clips. The tension knob devices in the pic, and the one laying at the bottom of the cabinet.

As to the bare buss, that's how it was; also the guage of the enclosure is probably double or more of today's enclosures.
