This may be an original design. i will look into my blocks books and see if it is listed. Only thing I might add would be to check with an antique quilt book or maybe APQS quilt restorer as to the best way to mend and determine the pattern used. I do know that any updates on fabric alter the date the quilt is valued at. The newer the fabric the newer the quilt and therefore the value would diminish. If you are serious about collecting you may want to consider this. Other than that....it is absolutely gorgeious and I , for one would love to have a copy of the pattern if you make one. Is that an eagle in the center?
