Found in use in an electrical service panel.
No overloads or maybe extra strong fuses?:shock:

Hi there
Very neat, no idea what they are but I love old stuff, did you see these that I found a while ago?

Those are strange ones.
The big one in my photo is marked pat 1916.
They came from a hose wired in 1905 updated to two fuses in 1926.
Those “turret” fuses are a real find. Thanks for sharing.
