old antique patchwork quilt top, 1800s vintage shirting fabric & red calico

Late 1800s or early 1900s vintage patchwork quilt top made of two beautiful old calico shirting fabrics, black and white, red and white. This is just a quilt TOP - hand sewn piecing in a windmill pattern - not a finished quilt.

It's been laundered (not recently), still has a few spots which might have been on the fabrics used to piece it. Size is about 71" x 80".
