Antique Brass Posidon Wall Lamps

I love this pair of very rare Brass Poseidon Lamps. I've never seen another pair anywhere. They are in good condition, the flame globes are in perfect condition. They are very heavy. Not sure where they came from but bought in an auction in London. Not sure of the age but as they are electric I assume around 1920-1930. Maker unknown as there are no marks.
Hope your all enjoying my collection. I may sell these as I live in Canada now and nowhere to install them.
