This is a George Hunzinger “Dining or Library Chair No. 44″ from the Kimball’s Book of Designs: Furniture and Drapery (Boston, 1876). I have a question into the seller of the chair on the right to see if the original wire, which you see clearly in the original catalog image, is retained behind the added upholstery.
Hunzinger states in his patent, “The chair seat or back is made with reference to the use of wire in place of cane, to form an open-work seat, and to insure great strength and beauty, and to facilitate the interweaving of the wires.”
The chair is stamped for two patents, the woven wire seating and front brace patents. There is also a rocking chair version of this design.
