I have an older book, 1988 titled The new Quilting & Patchwork Dictionary by Rhoda Goldberg, It has 3 swastika patterns included, each slightly different, but the one like your quilt is titled, Swastika3,Wind Power of Osages. I also have another older book with this pattern as well, unfortunate that one of the most villanous men of all time chose this design to represent his hateful regime.
