These "fuses" appear to be unmarked. Any idea as to their current carrying

Generic brand. Once size fits all.

Looking at the box outside I wonder if the box is just being incorrectly
used as a junction box and wires go to a fuse or breaker in the panel.

Quick disconnect. Its a feature!

If it is just a disconnect, that is perfectly legal, as long as there
is an OC device upstream. In fact they make "listed" pullouts that are
electrically identical. You might have one on your AC as we speak.
They also make "breakers" that are just switches for that same
purpose. (local disconnects). I have a bunch of them. You can tell
because there are no (amp rating) numbers on the handle.

Electrically, agree.

Does it not violate the Code "workmanship" clause in that the pieces of
pipe won't be listed by box manufacturer as being valid parts?

I get the disconnect; I don't see why not just use the fuses, though.
What would it hurt -- unless it was tripping the properly-sized fuses
and this is a bypass.

As I said in my note to Joyce, this picture has been bouncing around
for decades and it was pulled from a disconnect, not the branch
circuit overcurrent device. Certainly it is a 110.3(B) violation (not
a listed part for that fuse holder) but not a particular safety issue.
