It might not be clear from my post, but my Supermatic freearm takes GŁtermann top stitch thread too and sews through anything that fits under the presser foot. That is why I think the 19 and 21 can too, since they are strong and fast machines compared to any out there. GŁtermann has an equivalent larger cone of their top stitch thread, but it's called something else.
