Superb late 1800s antique French lantern lamp with verdi gris

My last listing today. I found this amazing 19th century French copper confection yesterday morning. Superb verdi gris and I think it was an old parafin lamp. Lamp or a greenhouse heater?
I'm sure it could be converted into a really unusual desk light table lamp. I love the acanthus leaf and the curled shape of the top
