There aren't too many US made square panel mount fuse holders.
Indeed. I've seen them, but they aren't ordinary.
There was another square faced panel mount fuse holder that used to be
pretty common but I can't remember who made it. I want to say it was
Mountain Switch but I don't think it was them. Unlike the Littelfuse 348
series, it has a round, threaded body with a small hole in the outer edge
of the square frame where you push a small screwdriver to release the
cap's locking tab.
It sounds like it might be a Littelfuse 348 series.

That looks like the thing. Thanks!
I couldn't tell from the grainy b/w photo I found online of the rear of
the terminal if it had a black or red fuse holder cap. They also made them
in a few other colors, but black and red were the most common.
One thing that will differ on the current production 348 series fuse
holder caps vs the vintage ones is they no longer have white paint for the
inset lettering (another victim of RoHS). You can simulate the original
effect with a white-out pen and just scratch off any excess outside the
recessed lettering with a fingernail.
