I'm going to chime in on the attachments, although there are many more knowledgeable people here than me. It's hard to tell about all from the jumble, but some are "low shank" attachments that will work on your machines: the pintucker, the ruffler that are outside the box and possibly the adjustable hemmer inside the box. The hemmer scrolls and the pintucker inside the box have the top clamping type of attachment that is used by several non singer rotary machines such as White, National, Standard, etc. The box may be labeled Rotary attachments or White on the top (or it may just say attachments as my White Family Rotary box does). These will not fit your Singer. It is very common, in my experience, to find a mixed bag of attachments with machines, even one owner machines. I suspect the original owners sometimes had attachments from mom's machine thrown in.
