Three near matching lamp bases clearly of the identical form but varying sizes and surface treatment. Tallest 21". Unmarked. We believe them to be the work of Empire though possibly Miller ~ you decide. CONDITION: Good to Very Good. Original sockets and pull chains though one has no sockets or wiring at all. Two are rewired relatively recently (we do not guarantee wiring in any way). Original surfaces relatively clean and intact though the verde green base does have significant loss of surface color at base. No finials and only one base has its upper cap.
