1880s vintage Rochester ornate antique brass oil lamp converted to electric light

Beautiful Victorian brass oil lamp marked The Rochester, with an 1886 patent date. This was converted to electricity, works fine, measures 11 1/2" to the top of the light bulb socket.

This has no chimney or glass shade - it's made to hold a shade 9" in diameter or a little smaller. It's in good condition, though we're not sure it could ever be converted back to a kerosene light.
