This is a WWII era sewing kit issued by the United States military. It is about 3″ tall. The lid holds a thimble. When opened up you will find a spool of thread with a little metal needle container that fits down the middle. Spare buttons fill the bottom of this one. Originally it may have had two spools of thread stacked up.
You can find this cool little collectible at the Albany Antique Mall, in Historic Downtown Albany Oregon.
