Let's "DATE THE QUILT"

Double Z, Old Maid's Puzzle, Brown Goose, Gray Goose, Devil's Claws, Framed X or Old Gray Goose. These are the names listed in Brackman's Encyclopedia of Pieced Quilt Patterns for the block used the the above antique quilt. The earliest is Framed X published in the Farm Journal in 1877. All blocks in this quilt are black prints and it is put together with dark blue. How about we have a little contest? Anyone want to date this quilt? I have my own idea, but would love to know yours. It is in extemely good condition.
