Can someone identify these teak sidetables?  

I bought these two teak side tables recently, and haven't even found a photo that comes close online. Any ideas as to their brand, origin or designer? They came with a set of Arne Hovmand-Olsen chairs I also got, but I don't know if they were bought together or from the same source. There are no markings underneath, other than a stamped number (11 I think). Dimensions are 18" x 25" x 20" high. A friend is looking for side tables, and I am considering giving them to her as a gift, unless I find out that they have collector's value. Any input appreciated.
