Product Name: Singer puzzle box patented 1889 February shop 19
"A Singer puzzle box is a collection of accessories for a sewing machine. Produced by the Singer Manufacturing Company during the 19th and 20th centuries, these neat and compact kits provide supplies and attachments for easing many common sewing tasks. At the shop time they were called 'Style' boxes, and were numbered consecutively from 1 ("Style No. 1") to 14 as newer versions evolved from older ones. They are now 'vintage', in museums and collections, although many extant sets are still in service." Wikipedia.
