I snatch up these brilliant accordian-type boxes made to hold sewing machine attachments whenever I find one because I love them so much! Patented in 1889, this oak wood box is constructed of four hinged parts with triangular shaped ends, which unfold to reveal a purple velveteen interior designed to hold Singer sewing machine attachments. (And this one came loaded with a full sets of parts, which I've removed as they make it pretty heavy--and full-- but I'll happily include them if desired.) It folds back up elegantly to form a rectangular box with square sides, snapping closed at the top.
The box features the original oak stain and mark on the front reading "Patented 1889, February 19."It's in very good vintage condition, with little wear to the finish in a few spots (I have not touched the wood), and measures 6 1/2" long by 3 3/8 inches wide and deep.
