Now on to the boxes.
I do not have style #1 - it is very different in that is has removable screws that hold the pieces into the box - it does not have the bar that all the rest have to hold the hemmer sets.
This is box #2 - while the mounting bar is the same as used in the later sets, it is mounted in the middle of the section. Also notice the middle holder on the three prong holder in the middle. It has curved edges to hold the small braider foot. Compare it to the middle holder in box 3 below, it's wider and flat to hold the hemmer attachment foot. Also note that box #2 has no clip to hold the underbraider in the left most section.
The rest is basically the same as style #3 (shown below)
The early boxes (1, 2, and 3) have a hook for closure. I have seen style 7 with both the hook and the latch.
Styles 8 to 11 have a latch. The copyright imprint is a bit farther back on the box, and it has the two pins visible from the outside - and the spring latch on the inside. It also has the grove in the lower section to make opening the box easier.
The bobbin holder for the VS styles is the same for all boxes. The IF holder has two styles,
On the left is the style for boxes 1-8, and the right is found on boxes 9-11.
The older style holder is actually too small to hold the bobbins that fit into the bobbin case. Early IF machines did not use a bobbin case, and used bobbins more similar to that used in the 66. It's also a bit limited because the bobbin has to be full of thread in order to stay put. Empty bobbins fall out.
