Singer Folding Wood Puzzle Box Attachments Treadle Sewing Machine Parts

Up for sale today is a great Singer sewing machine parts puzzle box with various miscellaneous parts. This box was found with a Singer Sphinx sewing machine though I have no idea if the parts can be used on that particular machine. The box shows lots of wear including scratches, one side of one of the hinges is detached, discoloration, damage to lining, etc. Some of the parts have serial numbers, at least one is stamped "Singer", and two of the retaining clips for the box have a serial number (the serial numbers from the parts do not match the box).
Please see pictures for details and ask any questions prior to purchase. I will be happy to supply additional information upon request. This box is being sold as is, and returns are not accepted.
Shipping will be by Priority Mail.
