this one mounts from the back.
Does provide for a good view of the work area.
This is the tucker that came with the set - it is very similar to the one for the Wheeler Wilson D9 I have.
There are no maker marks on any of the peices in this set. They are being modeled by my National Two Spool.
I have another ruffler just like this one, it came in a set for a White Rotary, unfortunately it IS identical, so it also fits the National. But I bought that other set for the extra bobbins and shuttle assembly that was in the box with the attachments.
