Looking for these or similar wood strips that were used as attachments to the tops of existing fences. Some were also screwed to the tops of barn gates and corrals.
They were used as alternatives to erecting new barb wire fences. Some were patented and others homemade.
They will eventually become a museum exhibit if enough are found.
Contact me if you find some pieces, know of any examples, or have even seen them currently on display in a local museum.
