no, and neither is the "blackside" stuff. Singer used the finishes as an alternate, they didn't consider them anything "special" at the time. Several other manufacturers use a "crinkle" type finish at that time too.
like you pointed out, it is rare with the 221 (crinkle) You can find 128 easily, and also 66. I don't think I've ever seen a 15 or 201 with an original crinkle finish.
