Viko by Baumritter? Knock-offs?  

I found these chairs at a thrift store in Statesville, NC. They are very reminiscent of Viko by Baumritter but have some definite differences. I am trying to figure out the maker. There is no manufacturer on the bottom of the chair. The materials tag is in tact but it does not list the maker either. All of the dates on the tag list the late 1920s. I know this references the material laws, but I have seen similar baumritter chairs with much later dates and similar materials. Does anyone have any knowledge to add? I feel like this may be an early set, or even prototypes. I live between the Maiden and Old Fort Ethan Allen production facilities. I am not sure how long these plants have been in existence. Sorry for only having one picture, but I am not home and cannot take more images.
