Mack owned Brockway for their 20 or so years of production before shutting them down in 1977. I still see them operated mostly as plow and farm trucks, not often road going.
There's a farm that has 30 or so Brockways. Many are work trucks. Some are restored. They are active in a Brockway historical association. Once I took a picture of them all in a row with a 90° bend. It was on a work phone and I lost the picture when I turned in the phone. The picture is of one of their trucks at one of my old oil customer's shop.
