Help me identify these Royere-like wrought iron chairs.  

I acquired these wrought iron lounge chairs earlier this year. Upon my research I have only come up with one hit from of an old 1stdibs listing via Pinterest . The only description of the chair was "vintage wrought iron in the style of Jean Royere" which was my first thought when I saw the chairs. The name Jean Royere would be a nice pedigree to attach to the chairs but as of now they're only mystery chairs that can't even even be attributed to Royere. I'm in the process of restoration and placing new cushions. Has anyone seen another example of these chairs in person or in a publication that might provide some info. A friend said they look French possibly from the 30's or 40s. Any information would be greatly appreciated.
