Back clamp attachments? what machine are these for?
 

I got these with a Singer Red Eye, along with a box of low shank attachments. The red eye is seized in the bobbin department :-( ... I am not going to be keeping it, I guess...

They came in an unlabelled singer-type box. Since I don't know what to call them, it is hard to google them! Bobbin holder at the far left.

The bobbin case is for an older Kenmore / White / National type machine. It looks just like the one on my Kenmore 117-812 which was made by White.

The feet and attachments look very very similar to the one on my Singer 9W-7. So without having them to try out I'd guess either a Wheeler and Wilson #9 or a Singer 9w-7.

Thank you!! Are these considered rare?

Joe is right. The attachments fit a 9W or W&W D9...they'll also fit a W&W 8. They're more of a "center bar" attachment than they are a "back clamp"....they insert into the presserbar and then are tightened down with a thumbscrew from the back.

Rare? No. They're a bit harder to come by than low shank Singer attachments, but they are out there and available. :)
