I don't own a 400W. I hope I can sell this on eBay.
I must admit, I haven't serviced many of these types of Singers. I have about ten of these. I found a website that sells them. Apparently the nut is no longer available. I have a couple with the nut attached.
These are in serviceable shape, I believe
Who knows what these fit? I think, perhaps, an end loading machine. Japanese. May fit one of the Singers.
I would love to see the machine that this fits.
Looks Brand New. I think it fits the 400W.
Drawers full of stuff: Guides and Hooks.
Most of the seam guides seem (pun intended) to be in decent shape. One is pretty rusty.
Most of the hooks were broken. Angst. These seem to be intact.
NIB Necchi Foot controller. The box isn't so new. A little bit of cleaning is all this will take
Connection for Necchi. No cord, yet.
Another NIB foot controller. This will fit any machine with that connection.
I found many many many slide plates. Many needle plates. I found some more industrial hooks which I believe will fit the 251 241 and 281. Perhaps also some Brother industrial machines.
I found some other bobbins, too. Class M. Nice Big ones. TWSS.
I was pretty thrilled when I found a complete hook assembly with a bobbin case for a feather weight. But upon careful inspection I found that the hook assembly was for a 301 (still useful) and the bobbin case was damaged. Sigh.
I found some walking feet, many other feet. Many many many industrial feet. I found a compensating foot which I think will fit my 31-15. Oh, yes, and the re-built Necchi motor that I put on the Necchi yesterday.
There is much more. I need a slide plate for a 66 but cannot find one. Thus my angst. I have a lot of stuff, some of it may be useful, but when I need something as simple as a 66 slide plate and can't find it, I wonder, WHAT HAVE I DONE?
