That's a beautiful quilt. I have quilts from my DH's mother & grandmother. Some of them were pieced on a sewing machine & hand quilted & they are at least 75 years old. So, even though a sewing machine was used it does not mean that it is not an old quilt. I think a lot of quilts were pieced on the sewing machine & then hand quilted. Yours looks hand quilted to me.
