Mystery Chairs - Breuer Influence?  

As will be evident I'm a bit of a novice - but recently purchased a set of the classic Breuer chrome and cane cantilever chairs to use around the dining table. The two arm chairs are similar but not matching, as seen in the photos. Not only is the cantilever reversed, the seat and back join, and the scale is slightly larger (diameter of chrome tube. The side chairs I bought from the same family probably date from the 70s - these appear a bit older. I'm interested in learning more about these unusual chairs so welcome any/all comments. thanks
