26" x 12" x 3" "Swing-o-matic Bump Gate". Patented by W.H. Koch, Minneapolis, Minnesota. Patent No.2,629,191 February 24, 1953 . Manufactured by International Steel Company, Minneapolis, Minnesota. Drive up with your vehicle, bump it and it swings open. Gravity returns it to the closed position after you pass through. No more getting out of the car or truck to open and close the gate. The model is in rough condition compared to some I've seen, but I am pleased to add it to my collection.
