And more boxes.
Style 7 and 8 are very similar - except for the tucker holder. 7 had two tabs and 8 has one.
These three are all style 7 (left is missing one of the tucker holders). The left two are VS - one with hook closure and one with latch - the right is the IF version. Of the two tucker holders, the one holder is to the far end, the other in the middle and lower down.
Here is the style 8 - it only has one tucker holder, and it's more centrally located.
This is another difference - the bump to hold the end of the tucker - styles 8, 9, 10 and 11 are all like this.
Box 9 is similar except for a very different ruffler/shirr plate holder.
From what I've seen - boxes 10 and 11 are the same. They have the same holders as box 8 and 9 except that holding the ruffler and shirr plate. The rest of the holders are the same.
I've seen boxes with the location of the underbraider and screwdriver holders swapped - I think that was dependent on who ever was installing them, and not specific to any style. There are also later versions of style #11 that has five digit part numbers stamped on the attachments, while the others have a single or two digit number that is more the location in the box than the part number.
