Looks like something that might have been made for a traveling dressmaker (yes, you used to hire people that would come to your house to sew and mend on your machine!). Or perhaps something made for a family member who sewed a lot and was the neat and tidy type.

I've never seen anything quite like it before, but it is certainly a sensible design. Value is going to be whatever a willing buyer will give you for it. If it's a very nice job of carpentry (and it looks like it might be), perhaps as high as $200, but likely lower.

very confusing step do a search with a search engine that will can assist

I was wondering if anyone knew anything about this old sewing accessories box. I can only post one picture so the outside is wood and leather, it folds to a very thin box that stands on its own on the floor. I can't find any markings or brand name on it. Does anyone have any ideas about how old it is? Thanks
