This probably isn't the correct place to ask this question but I figure you all have a lot of experience in very diverse areas and someone might recognize this mystery object.

We found 11 of these in an old grain/equipment storage barn that is probably close to a hundred years old.
It measures: 9-5/16" across the top 8-9/16" across the bottom 4-3/8" on each side
The side pieces are 5/8" wide Top and bottom pieces are 3/8" wide.
The top and bottom bars are inset into a notch in the side bars and held in place with one small brad at each corner.
It's hard to tell what the wood is. Maybe pine. It's very dried out and feels almost as light as balsa wood.
