Vintage bentwood rocking chair

Is this Thonet ? I cant tell I have looked and looked and cannot find any mark or sticker as one would expect. However its eye catching when I fist saw it I was mesmerize, it has every thing going for it the screws the leather and its patina lead me to believe that it isnt a 70s copy I wouldnt like to suggest that its an 1800s original. Definitely a nice addition to ones interior . 82 cm high, 51 cm wide and 97 cm long.
