These two old wooden pieces with metal hardware, which I believe were used to hook horses or mules up to wagons, carts or some such, were found at a local thrift shop.
Finds like this here in Fargo continue to surprise this former city girl from Milwaukee. At farm auctions it’s de rigueur to find such rustic things (where they are quickly snatched-up), but finding them at thrift shops still surprises me. I’m more used to finding them displayed on walls.
