1960s French or Danish Desk Lamp

Hello, I am a set designer in Los Angeles working on a still shoot. This lamp was selected as a hero prop and now I have to gain clearance from the designer/manufacturer. The store we purchased this piece from did not have any information on the lamp. The owner took a guess and said 1960s/50s French. That's it....

Anyone have any ideas? Designers/manufacturers for me to investigate further? Thanks.
