Mundus-Thonet-Kohn rocking chair

I ve had this rocking chair for some years now. It served me well rocking my baby's to sleep in the middle of the night. But now, I must admit I dont use it anymore. It takes up loads of space, and my taste for furniture changed over the years. So think I might get rid of it. Its made in the end of the 19th-begin of the 20th century. Its not signed, but an acquintance of mine who knows a lot about Thonet told me it could still be made by Thonet or Mundus Kohn. And she believed it was. Does anybody know how I can tell?
Thanks a lot!
