I have similar arms made by HAPCO . The only difference i can see is the HAPCOs don't have the small reinforcement plate between the arm and the under brace . https://www.lighting-gallery.net/gallery/displayimage.php?album=5198&pos=98&pid=165251
Collect vintage incandescent and fluorescent fixtures. Also like HID lighting and streetlights.
