This looks like an old recycled FPE panel. Notice all the extra missing KO's, the "Stab-Lok" buss and the plaster ring. I'd be willing to bet that the panel cover is long gone, though that's certainly among the least of the problems here. I'm trying to figure out what's going on with that cartridge fuse cutout at the top. It looks like some kind of afterthought that someone tried to cobble in there.

"Horrible" doesn't begin to describe this garbage [Linked Image].
