I was browsing a few of our local antique shops today and spotted this little gem. Its an unusual little wooden box that appears to be made to fit in a treadle cabinet drawer.

Wow! I have never seen anything like it.
Thanks for posting these pictures.
I love vintage sewing machines and attachments.

I have no idea what it is

check ebay - I've seen these on sale off and on. Can't remember what they go for. Not sure which machines they usually fit- likely just any Singer short shank.

we usually call them puzzle boxes tho that is a more modern name. From your picture they look like early back clamping attachments.

The second from the right might be a tucker and the last on the right might be an early all metal buttonholer. I think the scooped things might be hemmers.
All guesses tho!

If those flatend oval parts have a way to put fabric into them (slott)...they look to be binders...different size binding attachments. I have a box of them that go on my industrial machine. They screw onto the bed of the machine (usually a commercial/dressmaking/upholstery machine). The next to the last on the right looks to be part of a button hole guide, and the last on the right looks to be a ruffler. Why not check with the guy on here (Billy?) who does the vintage machine repair.

neat find!!

Isn't that a Singer box?

It is a Singer Puzzle Box with sewing attachments.

I had one of those...sold the puzzle box on Ebay a few years back for around $30.
