Took me awhile to figure out what this is. It's an antique drone bee trap. I believe this is manufactured and not hand made. Old weathered wood with original nails that have some rusting areas on the wood. The back lower grill slides out to release the insect. The bottom slat has breather holes and a chip in the wood. On the back is a small metal tab that you pull out to open the center hole. It is kind of tight so I did not remove it.

Measures 13" long, stands 4 1/2" high, 2 1/2" deep.
