Antique Singer Puzzle Box for Attatchments, Oak

Description

A most cleverly designed small, folding box to hold sewing machine attatchments.
This one has no attatchments, but the deep blue velvet lining begs for maybe a piece of jewelry?
Sturdy latch, clean, beautifully grained oak....this is a great little sculptural piece to display.
closed dimensions:  6.5" long, 3.25" deep, 3.25" tall.
Fully opened, it extends to 12".
