Here is something I have been meaning to mention. All embroidery work of this time period was done on machines that followed a strict pattern determined by a tape that worked much like the "tapes" used on old self-playing pianos. As to embroidery machines, the stitching needles would drop according to the hole patterns in the tape. So if a single stitch is off, it didn't come from the intital, master tape. These tapes were VERY hard to make, as it was done by hand, so I doubt if a manufacturer would have made two tapes for the same design. Even today it is expensive to have an embroidery guide "digitized." It's artwork, and its done by hand.
