Made in late 1920's in the factory of Mundus & J. J Kohn. No label/stamp visible. Lovely dark honey color 

Wear and tear as expected for its vintage status, a few indelible marks, splits and scuffs, slight shrinkage to the seats but the chair is stable and sturdy for daily use. The chairs have been lightly refurbished with Danish Oil and polished with bee-wax to enhance the patina. Do check the pictures for details to explain this description. 
 
This chair matches V. Bentwood and could easily be a pair.
