yep, the two main features are the extra skinny post that allows you to sew up to the tip of the ladies gloves and it uses a two thread "doublechain" pique stitch that is actually "stretchable" (similar to the Grover & Baker stitch) so that the gloves will stretch and give without popping seams.
The more modern version lists for 800-1500 used.... Still waiting to see an older one.
