Turns out there is another US manufacturer of hand sewing awls, buried (here) in the google search results.
Contrary to a belief expressed in another thread, it seems this century-old design, with bobbin up front, is not an earlier Speedy Stitcher, but from another company altogether.
Compare the offerings of thread, needles, and parts with those of Speedy Stitcher, and it isn't close. C.A. Myers wins, easily.
Unfortunately, it is all a blur to and the same to Sportsman's Guide, not the fault of Speedy Stitcher or C.A. Myers.
