I've seen fuse boxes in later structures in my other line of work. Around here a ton of folks will tear down & salvage out anything that they can use. Take this stuff and build a "new" home. I've even heard a couple of 'em bragging about how they built and bought nothing new except maybe shingles.
As far as the al wire in a fuse box, I'm not sure that any of those connections would be approved for AL wire, seems that the use of AL wire in branch circuits didn't come in until after fuse boxes had just about been phased out. There probably are some fuse boxes that were rated for AL wiring, but I can't recall seeing any, if these don't bear a legend stating that they are approved for AL I would suspect that they aren't.
Oh yeah, my other line of work for the last 20 something years has been with the local fire department. I see fuse boxes and the bad decisions that often go with them all the time.
