Bernardaud & Co operated from 1914 to 1930 from what I could find !! Not sure if they were absorbed into another company or not !! If that old I assume your lamps have been rewired at some time !! Values are pretty good at $300.+ asking price for a single lamp !! You have a pair so should be in the $400. to $500. range but as with anything else,, its only worth what someone is willing to pay for it !! In todays market I would say the pair would bring closer to $300. !! Remember lamps are not a collectible item,, they are meant to use !! These lamps may not go with everyones decor !!
