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.
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.
