Can you solve this mystery?
 

A friend has this vintage Singer all cleaned up and working,. One of the attachments is a mystery to us both! [ATTACH=CONFIG]617797[/ATTACH][ATTACH=CONFIG]617798[/ATTACH] see piece which blue arrow points to, the round one.

:confused:??? That is unusual. I hope Macybaby sees this.

Most of those feet will not fit the Singer. I don't know which machine they will fit. I'm pretty sure I've seen the underbraider but don't remember which machine it is for. I'm going to guess it might be for darning or free motion as it looks like it would hold the fabric near the needle so that the fabric stays put while the needle is on the upstroke.

There seems to be a piece that is attached to the ring...maybe fits under that hump where needle hole is?

You've got a book for a Singer and a box of attachments for a top clamp, so most of them will fit your machine. I only see a few side clamp feet. I must be getting rusty, I can't remember which one uses the "S" looking underbraider! OK- I looked at my pictures, that would be a National made machine.

I've not seen that round one before, but it does attach to the presser foot and has a needle hole. it's sort of like a super wide foot, but nothing like a darning (FM) foot. Most of those attach to the needle bar and don't use the presser foot at all.

The piece attached to the ring is how it clamps to the presser foot - just like all the other attachments have.

The piece that is on the upper left side about 11 o'clock position appears to be just laying on it and not attached. That piece is part of an adjustable hemmer.

Looks like Cathy answered about the same time.

I surely hate to see the WD40 can near a VSM.

Too late to edit - but I missed a word - most of the will Not fit your machine!!!!!

I'm not sure what postage would be, but I'd be willing to trade you a set that fits your machine for the set you have - or more specifically, for the one foot you have questioned, since that is one I don't own yet :)

Macybaby, and leon f, this is not my machine. My friend got this one running using the wd40 as a last ditch effort as it was totally seized.She knows about proper lubrication, uses clear light machine oil. She owns 5 other vintage Singers and a vintage Pfaff , and has restored them all from very sad mechanical condition....now uses each in turn regularly. She will likely have a machine to fit the accessories. But that mystery still remains...what the heck is that round piece used for? My guess was for sewing channels in down comforters...but who knows for sure?

It looks to me to be some kind of needle plate. It's hard to tell from the 2 pics, but can the round mystery attachment fit into where the cover plate goes? Looks like a needle hole in it, so I am guessing that's what it's for.

If your friend has a National made rotary machine, then she'll have one that fits. National and White both use a center needle, but White has a bit more distance between the presser bar and needle bar. Standard has an offset needle hole and Free has a narrower top clamp so these would fit very loose. There are a lot more options for older sets of top clamp attachments, but this is a later set when most of the other companies were out of business. Greist was making most of the top clamp accessories at that time.

I've got way, way more attachments than I have machines for, and I've got over 150 of them! And even though I really don't need anything more, I still get tempted when I see something I don't have lol!
