Question about old hay wagon
I found this old wagon and am trying to make heads or tales of it. It appears to be an old hay wagon or bundle wagon of some sort. It has a hay rack that fold up on the front. However, in the center of the wagon, the boards are missing, and don't appear to ever have any. There are then three boards that are recessed down in it. Kind of strange for a hay wagon to have a big gap in the center Does anyone have any idea of what type of wagon this is, or why there is a gap in the center?
