I think one of the difficulties in identifying the block from historic source material is the nature of the block. While there is a block (see my markings on the photo), that is not the way the creator made the quilt. And because it was hand sewn, there is less of a bright line between pieced and appliqué. The crown makes me think that it is possible it was started in 1936 to commemorate the coronation of King Edward 8 or King George 7.
