Antique vintage Victorian early electric nickel plated 2024 brass bathroom sconce light fixture Holophane shade

Simple but oddly hard to find nickel sconce from about 1910. There is one pin hole near 2024 the slip collar. The collar is not attached to the canopy so you can rotate the screw around and it almost covers it. I converted the arm to 1/8 IP so it works on a modern strap crossbar. 4 5/8" canopy. Nice Holophane shade. New wiring.
